Bluetooth: hci_sync: call destroy in hci_cmd_sync_run if immediate

hci_cmd_sync_run() may run the work immediately if called from existing
sync work (otherwise it queues a new sync work). In this case it fails
to call the destroy() function.

On immediate run, make it behave same way as if item was queued
successfully: call destroy, and return 0.

The only callsite is hci_abort_conn() via hci_cmd_sync_run_once(), and
this changes its return value. However, its return value is not used
except as the return value for hci_disconnect(), and nothing uses the
return value of hci_disconnect(). Hence there should be no behavior
change anywhere.
