irqdomain: Drop bogus fwspec-mapping error handling

stable inclusion
from stable-v5.10.173
commit 306c8b49b5666856dfe74d032e2dc5ac17d3784e
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I8BFR3

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=306c8b49b5666856dfe74d032e2dc5ac17d3784e



--------------------------------

commit e3b7ab02 upstream.

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: 1e2a7d78 ("irqdomain: Don't set type when mapping an IRQ")
