Default ene_ir: Fix driver initialisation

commit 9ef449c6b31bb6a8e6dedc24de475a3b8c79be20 ("[media] rc: Postpone ISR
registration") fixed an early ISR registration on several drivers. It did
however also introduced a bug by moving the invocation of pnp_port_start()
to the end of the probe function.

This patch fixes this issue by moving the invocation of pnp_port_start() to
an earlier stage in the probe function.
