Kristian Nielsen 60d094aeac MDEV-7936: Assertion `!table || table->in_use == _current_thd()' failed on parallel replication in optimistic mode ...

Make sure that in parallel replication, we execute wait_for_prior_commit()
before setting table->in_use for a temporary table. Otherwise we can end up
with two parallel replication worker threads competing with each other for
use of a temporary table.

Re-factor the use of find_temporary_table() to be able to handle errors
in the caller (as wait_for_prior_commit() can return error in case of
deadlock kill).
