Johan Hovold e3b7ab025e irqdomain: Drop bogus fwspec-mapping error handling
In case a newly allocated IRQ ever ends up not having any associated
struct irq_data it would not even be possible to dispose the mapping.

Replace the bogus disposal with a WARN_ON().

This will also be used to fix a shared-interrupt mapping race, hence the
CC-stable tag.

Fixes: 1e2a7d7849 ("irqdomain: Don't set type when mapping an IRQ")
