doc: Remove incorrect note about wal_status in pg_replication_slots.

The documentation previously stated that the wal_status column is NULL
if restart_lsn is NULL in the pg_replication_slots view. This is incorrect,
and wal_status can be "lost" even when restart_lsn is NULL.

This commit removes the incorrect description.

Back-patched to all supported versions.
