[media] lirc_zilog: Remove unneeded tests for existence of the IR Tx function 



The driver is now structured so that it must handle an IR Tx unit
for a Z8 IR chip, or it refuses to handle that Z8 IR chip.  This
allows us to assume that ir->tx != NULL in a few places in the driver,
and also allows us to always report Tx is available to userspace.
Get rid of unneeded tests for ir->tx == NULL and always report that
Tx is available.
