Xin Long 004973021d Revert "sctp: remove sctp_transport_pmtu_check" ...

[ Upstream commit 69fec325a6 ]

This reverts commit 22d7be267e.

The dst's mtu in transport can be updated by a non sctp place like
in xfrm where the MTU information didn't get synced between asoc,
transport and dst, so it is still needed to do the pmtu check
in sctp_packet_config.
