vfio/pci: Consolidate irq cleanup on MSI/MSI-X disable
vfio_msi_disable() releases all previously allocated state associated with each interrupt before disabling MSI/MSI-X. vfio_msi_disable() iterates twice over the interrupt state: first directly with a for loop to do virqfd cleanup, followed by another for loop within vfio_msi_set_block() that removes the interrupt handler and its associated state using vfio_msi_set_vector_signal(). Simplify interrupt cleanup by iterating over allocated interrupts once.
