irqchip/irq-msi-lib: Free wired MSI descriptors
msi_device_domain_alloc_wired() allocates a descriptor for each
interrupt, but wired MSI domains do not set MSI_FLAG_FREE_MSI_DESCS.
msi_device_domain_free_wired() releases the IRQ without freeing its
descriptor, eventually exhausting the domain. Failed allocations also
leave descriptors behind.
Set MSI_FLAG_FREE_MSI_DESCS for wired MSI domains so both paths
release the descriptors.
