    bufmgr: Return whether WaitReadBuffers() needed to wait
    
    Thanks to the previous commit, pgaio_wref_check_done() will now detect whether
    IO has completed even if userspace has not yet consumed the kernel completion.
    This knowledge can be useful for callers of WaitReadBuffers() to know whether
    it needed to wait or not, e.g. for adjusting read-ahead aggressiveness or for
    instrumentation.
