We were asserting that a txn closure doesn't declare success if the txn
is marked as ABORTED. Some sort of error is generally expected in that
case.
Unfortunately, the assertion is naive. The proto can be marked as
ABORTED async by the heartbeat loop, in which case the client only finds
out on the imminent commit attempt.
Fix #28743
Release note: bug fix: fix a rare crash with the message "no err but
aborted txn proto"
