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.
