Kristian Nielsen 4c8af2007d MDEV-36934: semi sync makes the master unresponsive when a replica is stopped 
Ensure that a pending semi-sync transaction can only be signalled on its THD
while it is waiting in commit_trx(); not if the wait in commit_trx() is
skipped for some reason.

There was a bug that if no semi-sync slaves were connected and
rpl_semi_sync_master_wait_no_slave was off, the THD pointer could be left in
the list of pending transactions after THD was deleted, and an invalid
THD/condition variable could be signalled, causing hang or other corruption.

Testcase based on work by Brandon Nesterenko <brandon.nesterenko@mariadb.com>.
