pgsql: Fix harmless leftover in _hash_kill_items()

Fix harmless leftover in _hash_kill_items()

Checking for 'havePin' is sufficient here. An earlier version of the
patch didn't have the 'havePin' variable and used
'so->hashso_bucket_buf == so->currPos.buf' as the condition when both
locking and unlocking the page. The havePin variable was added later
during development, but the unlocking condition wasn't fully
updated. Tidy it up.
