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.
