__setup_msi_irq() needs to undo what it did before calling

map_domain_pirq() needs to get rid of the MSI descriptor it
(implicitly) allocated. The case of a setup_msi_irq() failure on a
non-initial multi-vector-MSI interrupt needs special handling: While
the initial IRQ will get freed by the caller (who also passed it to
us), we need to undo the effect setup_msi_irq() had on it. (As a
benefit from the added call to msi_free_irq() we no longer need to
explicitly call destroy_irq() on the non-initial slots.)
