Mark Johnston e6c19aa94d sctp: Allow blocking on I/O locks even with non-blocking sockets 
There are two flags to request a non-blocking receive on a socket:
MSG_NBIO and MSG_DONTWAIT.  They are handled a bit differently in that
soreceive_generic() and soreceive_stream() will block on the socket I/O
lock when MSG_NBIO is set, but not if MSG_DONTWAIT is set.  In general,
MSG_NBIO seems to mean, "don't block if there is no data to receive" and
MSG_DONTWAIT means "don't go to sleep for any reason".

SCTP's soreceive implementation did not allow blocking on the I/O lock
if either flag is set, but this violates an assumption in
aio_process_sb(), which specifies MSG_NBIO but nonetheless
expects to make progress if data is available to read.  Change
sctp_sorecvmsg() to block on the I/O lock only if MSG_DONTWAIT
is not set.
