[PATCH 3.16 120/157] ufs: fix braino in ufs_get_inode_gid() for solaris UFS flavour

[Ben Hutchings]

3.16.72-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Al Viro <viro@xxxxxxxxxxxxxxxxxx>

commit 4e9036042fedaffcd868d7f7aa948756c48c637d upstream.

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().
