[media] lirc_zilog: Restore checks for existence of the IR_tx object

This reverts commit 8090232a237ab62e22307fc060097da1a283dd66 and
adds an additional check for ir->tx == NULL.

The user may need us to handle an RX only unit.  Apparently
there are TV capture units in existence with Rx only wiring
and/or RX only firmware for the on-board Zilog Z8 IR unit.
