cifs: do not use uninitialized data in the owner/group sid

[ Upstream commit 26d3dadebbcbddfaf1d9caad42527a28a0ed28d8 ]

When idsfromsid is used we create a special SID for owner/group.
This structure must be initialized or else the first 5 bytes
of the Authority field of the SID will contain uninitialized data
and thus not be a valid SID.
