SF: Prevent non-sync transactions from syncing

Clears the sync handle and frame number after registering a deferred
transaction to prevent other non-synchronized transactions from
erroneously getting marked as synchronized.

Also changes the application of pending states such that all valid
pending transactions are applied instead of breaking after the first
one.
