ceph: remove unnecessary IS_ERR() check in ceph_fname_to_usr()
Before returning, function ceph_fname_to_usr() does a final IS_ERR() check
in 'dir':
if ((dir != fname->dir) && !IS_ERR(dir)) {...}
This check is unnecessary because, if the 'dir' variable has changed to
something other than 'fname->dir' (it's initial value), that error check has
been performed already and, if there was indeed an error, it would have
been returned immediately.
Besides, this useless IS_ERR() is also confusing static analysis tools.
