Revert "genirq/irqdomain: Don't try to free an interrupt that has no mapping"

Browse Source 
* This is retard. An interrupt does not have a permanent virq. The virq of an irq may be changed
after the free of other irqs.

* This is causing problems for msm_msi_irq_domain to free all the irqs that it allocated.

* Fix unrecoverable modem crash.

This reverts commit d1874e36cb3d00ba53f9e7bc3ca58d3058659cee.
