[PATCH] PCI/MSI: Fix msi_desc->affinity memory leak when freeing MSI IRQs.

[PATCH] PCI/MSI: Fix msi_desc->affinity memory leak when freeing MSI IRQs.

[Prarit Bhargava]

During device setup, msix_setup_entries() and msi_setup_entry() allocate
msi_desc by calling alloc_msi_entry().  alloc_msi_entry() can also allocate a
affinity cpumask.  During device teardown free_msi_irqs() is called and the
msi_desc is freed, but the affinity cpumask is leaked.

Fix it by calling free_msi_entry() which frees both the msi_desc and the
affinity cpumask.
