irqchip/mbigen: Don't clear eventid when freeing an MSI
mbigen_write_msg clears eventid bits of a mbigen register
when free a interrupt, because msi_domain_deactivate memset
struct msg to zero. Then multiple mbigen pins with zero eventid
will report the same interrupt number.
The eventid clear call trace:
free_irq
__free_irq
irq_shutdown
irq_domain_deactivate_irq
__irq_domain_deactivate_irq
__irq_domain_deactivate_irq
msi_domain_deactivate
platform_msi_write_msg
mbigen_write_msg
