ksmbd: Could not get encryption key
CIFS: VFS: cifs_put_smb_ses: Session Logoff failure rc=-512

Session lookup fails in ksmbd_get_encryption_key() because sess->state is
set to SMB2_SESSION_EXPIRED in session logoff. There is no need to do
session lookup again to encrypt the response. This patch change to use
ksmbd_session in ksmbd_work.

strtolower() corrupts all UTF-8 share names that have a byte in the C0
(À ISO8859-1) to DE (Þ ISO8859-1) range, since the non-ASCII part of
ISO8859-1 is incompatible with UTF-8. Prevent this by checking that a
byte is in the ASCII range with isascii(), before the conversion to
lowercase with tolower(). Properly handle case-insensitivity of UTF-8
share names by casefolding them, but fallback to ASCII lowercase
conversion on failure or if CONFIG_UNICODE is not set. Refactor to move
the share name casefolding immediately after the share name extraction.
Also, make the associated constness corrections.

new type safe helpers that operate on vfs{g,u}id_t.

if iterate_dir() returns non-negative value, caller has to treat it
as normal and check there is any error while populating dentry
information. ksmbd doesn't have to do anything because ksmbd already
checks too small OutputBufferLength to store one file information.

And because ctx->pos is set to file->f_pos when iterative_dir is called,
remove restart_ctx(). And if iterate_dir() return -EIO, which mean
directory entry is corrupted, return STATUS_FILE_CORRUPT_ERROR error
response.

This patch fixes some failure of SMB2_QUERY_DIRECTORY, which happens when

 "Here's the last batch of clk driver fixes for this release.

  These patches fix serious problems, for example, i.MX has an issue
  where changing the NAND clk frequency hangs the system. On Allwinner

  damage.

  And finally on some Broadcom SoCs the serial console stopped working
  because the clk tree hierarchy description got broken by an
  inadvertant DT node name change. That's fixed by using
  'clock-output-names' to generate a stable and unique name for clks so
  the framework can properly link things up.

  There's also a couple build fixes in here. One to fix CONFIG_OF=n
  builds and one to avoid an array out of bounds bug that happens during
  clk registration on microchip. I hope that KASAN would have found that
  OOB problem, but probably KASAN wasn't attempted. Instead LLVM/clang
