irqdomain: Fix disassociation race
The global irq_domain_mutex is held when mapping interrupts from
non-hierarchical domains but currently not when disposing them.
This specifically means that updates of the domain mapcount is racy
(currently only used for statistics in debugfs).
Make sure to hold the global irq_domain_mutex also when disposing
mappings from non-hierarchical domains.
Fixes: 9dc6be3d4193 ("genirq/irqdomain: Add map counter")
