SCTP: avoid assert on partial SCTP message

The receive buffer for SCTP, before this branch, is 8192. If a message
is larger, we receive only a partial message, which makes the gNB abort.
Remove the abort to not be susceptible to a message intended to crash
the gNB.

also, increase the receive buffer to be more forgiving for large messages

Closes: #920
