lio_listio: Don't post a completion notification if none was requested
One is allowed to use LIO_NOWAIT without specifying a sigevent. In this
case, lj->lioj_signal is left uninitialized, but several code paths
examine liov_signal.sigev_notify to figure out which notification to
post. Unconditionally initialize that field to SIGEV_NONE.
Add a dumb test case which triggers the bug.
