Thomas Gleixner 0f62d941ac genirq/msi: Provide msi_domain_alloc/free_irqs_descs_locked()
Usage sites which do allocations of the MSI descriptors before invoking
msi_domain_alloc_irqs() require to lock the MSI decriptors accross the
operation.

Provide entry points which can be called with the MSI mutex held and lock
the mutex in the existing entry points.
