Make HEAP_LOCK/HEAP2_LOCK_UPDATED replay reset HEAP_XMAX_INVALID.

0ac5ad5 started to compress infomask bits in WAL records. Unfortunately
the replay routines for XLOG_HEAP_LOCK/XLOG_HEAP2_LOCK_UPDATED forgot to
reset the HEAP_XMAX_INVALID (and some other) hint bits.

Luckily that's not problematic in the majority of cases, because after a
crash/on a standby row locks aren't meaningful. Unfortunately that does
not hold true in the presence of prepared transactions. This means that
after a crash, or after promotion, row level locks held by a prepared,
but not yet committed, prepared transaction might not be enforced.

Backpatch: 9.3, the oldest branch on which 0ac5ad5 is present.
