Log the correct ending timestamp in recovery_target_xid mode.
When ending recovery based on recovery_target_xid matching with
recovery_target_inclusive = off, we printed an incorrect timestamp
(always 2000-01-01) in the "recovery stopping before ... transaction"
log message. This is a consequence of sloppy refactoring in
c945af80c: the code to fetch recordXtime out of the commit/abort
record used to be executed unconditionally, but it was changed
to get called only in the RECOVERY_TARGET_TIME case. We need only
flip the order of operations to restore the intended behavior.
Per report from Torsten Förtsch. Back-patch to all supported
branches.
