libceph: reject preamble if control segment is empty
While head_onwire_len() has a branch to handle ctrl_len == 0 case,
prepare_read_control() always sets up a kvec for the CRC meaning that
a non-empty control segment is effectively assumed. All frames that
clients deal with meet that assumption, so let's make it official and
treat the preamble with an empty control segment as malformed.
