[PATCH AUTOSEL 3.18 5/6] ufs: fix braino in ufs_get_inode_gid() for solaris UFS flavour

[Sasha Levin]

From: Al Viro <viro@xxxxxxxxxxxxxxxxxx>

[ Upstream commit 4e9036042fedaffcd868d7f7aa948756c48c637d ]

To choose whether to pick the GID from the old (16bit) or new (32bit)
field, we should check if the old gid field is set to 0xffff.  Mainline
checks the old *UID* field instead - cut'n'paste from the corresponding
code in ufs_get_inode_uid().
