irqdomain: Fix association race
The sanity check for an already mapped virq is done outside of the
irq_domain_mutex-protected section which means that an (unlikely) racing
association may not be detected.
Fix this by factoring out the association implementation, which will
also be used in a follow-on change to fix a shared-interrupt mapping
race.
Fixes: ddaf144c61da ("irqdomain: Refactor irq_domain_associate_many()")
