Reinette Chatre e6cc6f1755 PCI/MSI: Clarify usage of pci_msix_free_irq() 
pci_msix_free_irq() is used to free an interrupt on a PCI/MSI-X interrupt
domain.

The API description specifies that the interrupt to be freed was allocated
via pci_msix_alloc_irq_at().  This description limits the usage of
pci_msix_free_irq() since pci_msix_free_irq() can also be used to free
MSI-X interrupts allocated with, for example, pci_alloc_irq_vectors().

Remove the text stating that the interrupt to be freed had to be allocated
with pci_msix_alloc_irq_at(). The needed struct msi_map need not be from
pci_msix_alloc_irq_at() but can be created from scratch using
pci_irq_vector() to obtain the Linux IRQ number. Highlight that
pci_msix_free_irq() cannot be used to disable MSI-X to guide users that,
for example, pci_free_irq_vectors() remains to be needed.
