ksmbd: use memcmp() to compare ClientGUIDs
ClientGUID is a fixed-size binary value and can contain embedded NUL
bytes. strncmp() stops comparing at the first NUL byte, so different
ClientGUID values can incorrectly be treated as equal.
Use memcmp() in SMB3 multichannel session binding and
FSCTL_VALIDATE_NEGOTIATE_INFO to compare all SMB2_CLIENT_GUID_SIZE
bytes.
Fixes: f5a544e3bab7 ("ksmbd: add support for SMB3 multichannel")
Fixes: e2f34481b24d ("cifsd: add server-side procedures for SMB3")
