cifs: fix set of group SID via NTSD xattrs

BugLink: https://bugs.launchpad.net/bugs/2036450

'setcifsacl -g <SID>' silently fails to set the group SID on server.

Actually, the bug existed since commit 438471b ("CIFS: Add support
for setting owner info, dos attributes, and create time"), but this fix
will not apply cleanly to kernel versions <= v5.10.

Fixes: 3970acf ("SMB3: Add support for getting and setting SACLs")
