ceph: silence smatch warning in reconnect_caps_cb()
Smatch static checker warning:
fs/ceph/mds_client.c:3968 reconnect_caps_cb()
warn: missing error code here? '__get_cap_for_mds()' failed. 'err' = '0'
[ idryomov: Dan says that Smatch considers it intentional only if the
"ret = 0;" assignment is within 4 or 5 lines of the goto. ]
