AES-CTR is using a counter 8bytes-8bytes what miss match with
kernel specs.

In the previous code a vadduwm was done to increment counter.
Replacing this for a vadduqm now considering both cases counter
8-8 bytes and full 16bytes.

The probe error path for this driver, for all intents and purposes,
is the talitos_remove() function due to the common "goto err_out".

Without this patch applied, talitos_remove() will panic under these
two conditions:

1. If the RNG device hasn't been registered via
   talitos_register_rng() prior to entry into talitos_remove(),
   then the attempt to unregister the RNG "device" will cause a panic.

2. If the priv->chan array has not been allocated prior to entry
   into talitos_remove(), then the per-channel FIFO cleanup will panic
   because of the dereference of that NULL "array".

Both of the above scenarios occur if talitos_probe_irq() fails.

This patch resolves issue #1 by introducing a boolean to mask the
hwrng_unregister() call in talitos_unregister_rng() if RNG device
registration was unsuccessful.

It resolves issue #2 by checking that priv->chan is not NULL in the
per-channel FIFO cleanup for loop.
