ParadoxV5 5b1bdf6076 MDEV-36359: Patch NULL deref after disabling Semi-Sync primary 
Under `@@rpl_semi_sync_master_wait_no_slave = 0`,
when `rpl_semi_sync_master_clients` decrements to zero, the primary
reverts to async replication. This code did not check whether Semi-
Sync is still globally enabled or not as it didn’t matter before.

However, after MDEV-33551 (#3089) split the transactions’ACK condition
variables to per-transaction, this function now needs Semi-Sync’s
transaction tracker to unblock these condition variables in batch,
but this tracker is `NULL` when Semi-Sync Primary is disabled.
