sctp: recvmsg should be able to run even if sock is in closing state

Browse source

Commit d46e416c11 missed to update some other places which checked for
the socket being TCP-style AND Established state, as Closing state has
some overlapping with the previous understanding of Established.

Without this fix, one of the effects is that some already queued rx
messages may not be readable anymore depending on how the association
teared down, and sending may also not be possible if peer initiated the
shutdown.

Also merge two if() blocks into one condition on sctp_sendmsg().
