irqchip/mbigen: Free msi_desc on device teardown 

commit edfc23f6f9 upstream.

Using irq_domain_free_irqs_common() on the irqdomain free path will
leave the MSI descriptor unfreed when platform devices get removed.
Properly free it by MSI domain free function.

Fixes: 9650c60ebf ("irqchip/mbigen: Create irq domain for each mbigen device")
