This bit should've been removed - and the bit it is modifying was removed by
commit b774302e885697dde027825f8de9beb985d037bd which is now upstream.
The invocation of cifs_fscache_get_super_cookie() added by that commit should
be altered to make it conditional.
To this end, I've rebased the patch on linus/master and something
approximating the attached change needs to be made.
