Ilya Dryomov 8aaff15168 ceph: avoid a use-after-free in ceph_destroy_options()
syzbot reported a use-after-free in ceph_destroy_options(), called from
ceph_mount().  The problem was that create_fs_client() consumed the opt
pointer on some errors, but not on all of them.  Make sure it always
consumes both libceph and ceph options.
