Qiang Yu acc5495bf7 bus: mhi: host: Fix up null pointer access in mhi_irq_handler 
The irq handler for a shared IRQ ought to be prepared for running
even now it's being freed. So let's check the pointer used by
mhi_irq_handler to avoid null pointer access since it is probably
released before freeing IRQ.

Fixes: 1227d2a20c ("bus: mhi: host: Move IRQ allocation to controller registration phase")
