Revert "sctp: remove sctp_transport_pmtu_check" [ Upstream commit 69fec325a64383667b8a35df5d48d6ce52fb2782 ] This reverts commit 22d7be267eaa8114dcc28d66c1c347f667d7878a. 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.
