Bug happens when a data size less than SHA block size is passed.
Since first attempt will be saved in buffer, second round attempt
get into two step to calculate op.inlen and op.outlen. The issue
resides in this step. A  wrong value of op.inlen and outlen was being
calculated.

This patch fix this eliminate the nx_sha_build_sg_list, that is
useless in SHA's algorithm context. Instead we call nx_build_sg_list
directly and pass a previous calculated max_sg_len to it.

In NX we need to pass always a 16 multiple size nx_sg_list to
co processor. Trim function handle with this assuring all nx_sg_lists
are 16 multiple size, although data was not being considerated when
crop was done. It was causing an unalignment between size of the list
and data, corrupting csbcpb fields returning a -23 H_ST_PARM error, or
invalid operation.

This patch fix this recalculating how much data should be put back
in to_process variable what assures the size of sg_list will be
correct with size of the data.

When the user explicitly states that they don't care whether the
algorithm has been tested (type = CRYPTO_ALG_TESTED and mask = 0),
there is a corner case where we may erroneously return ENOENT.

This patch fixes it by correcting the logic in the test.

This patch also removes a bogus inclusion of algapi.h which should

There is currently a large ifdef FIPS code section in proc.c.
Ostensibly it's there because the fips_enabled sysctl sits under
/proc/sys/crypto.  However, no other crypto sysctls exist.

In fact, the whole ethos of the crypto API is against such user
interfaces so this patch moves all the FIPS sysctl code over to
fips.c.

Initialising the RNG in drbg_kcapi_init is a waste of precious
entropy because all users will immediately seed the RNG after
the allocation.

In fact, all users should seed the RNG before using it.  So there
is no point in doing the seeding in drbg_kcapi_init.

This patch removes the initial seeding and the user must seed
the RNG explicitly (as they all currently do).

This patch also changes drbg_kcapi_reset to allow reseeding.
That is, if you call it after a successful initial seeding, then
it will not reset the internal state of the DRBG before mixing
the new input and entropy.

If you still wish to reset the internal state, you can always
free the DRBG and allocate a new one.

Finally this patch removes locking from drbg_uninstantiate because
it's now only called from the destruction path which must not be
executed in parallel with normal operations.
