Fix incomplete backpatch of pg_multixact truncation changes to <= 9.2
The backpatch of a95335b544d9c8377e9dc7a399d8e9a155895f82 to 9.2, 9.1
and 9.0 was incomplete, missing changes to xlog.c, primarily the call
to TrimMultiXact(). Testing presumably didn't show a problem without
these changes because TrimMultiXact() performs defense-in-depth work,
which is not strictly necessary.
It also missed moving StartupMultiXact() which would have been
problematic if a restartpoing happened in exactly the wrong moment,
causing a transient error.
