Paulo Alcantara ee0fb9baa7 smb: client: fix parsing of SMB3.1.1 POSIX create context 
[ Upstream commit 76025cc228 ]

The data offset for the SMB3.1.1 POSIX create context will always be
8-byte aligned so having the check 'noff + nlen >= doff' in
smb2_parse_contexts() is wrong as it will lead to -EINVAL because noff
+ nlen == doff.

Fix the sanity check to correctly handle aligned create context data.
