GFS2: Fix sgid propagation when using ACLs
This cleans up the mode setting code when creating inodes. The SGID bit was being reset by setattr_copy() when the user creating a subdirectory was not in the owning group. When ACLs are in use this SGID bit should have been propagated if the ACL allows creation of a subdirectory. GFS2's behaviour now matches that of the other ACL supporting filesystems in this regard.
