Add protocol specific operation for CIFS xattrs
commit d979f3b0a1f0b5499ab85e68cdf02b56852918b6 upstream. Changeset 666753c3ef8fc88b0ddd5be4865d0aa66428ac35 added protocol operations for get/setxattr to avoid calling cifs operations on smb2/smb3 mounts for xattr operations and this changeset adds the calls to cifs specific protocol operations for xattrs (in order to reenable cifs support for xattrs which was temporarily disabled by the previous changeset. We do not have SMB2/SMB3 worker function for setting xattrs yet so this only enables it for cifs. CCing stable since without these two small changsets (its small coreq 666753c3ef8fc88b0ddd5be4865d0aa66428ac35 is also needed) calling getfattr/setfattr on smb2/smb3 mounts causes problems.
