[PATCH v3 net-next] staging: irda: fix init level for irda core

When moving the IRDA code out of net/ into drivers/staging/irda/net, the
link order changes when IRDA is built into the kernel. That causes a
kernel crash at boot time as netfilter isn't initialized yet.

To fix this, move the init call level of the irda core to be
device_initcall() as the link order keeps this being initialized at the
correct time.

v3 - just change the initcall level, works so much simpler, thanks to
DaveM for the idea.
v2 - don't force irda to be a module, make the Makefiles put irda back
where it was before in the link order.
