migrate, tcp: More careful marshalling of mss parameter during migration
During migration we extract the limit on segment size using TCP_MAXSEG,
and set it on the other side with TCP_REPAIR_OPTIONS. However, unlike most
32-bit values we transfer we transfer it in native endian, not network
endian. This is not correct; add it to the list of endian fixups we make.
In addition, while MAXSEG will be 32-bits in practice, and is given as such
to TCP_REPAIR_OPTIONS, the TCP_MAXSEG sockopt treats it as an 'int'. It's
not strictly safe to pass a uint32_t to a getsockopt() expecting an int,
although we'll get away with it on most (maybe all) platforms. Correct
this as well.
