Make pci_enable_msix() and pci_enable_msi_block() consistent
with regard to the type of 'nvec' argument. Indeed, a number
of vectors to allocate is a natural value, so make it unsigned.

Calling this function asks the PCI subsystem to allocate 'nvec' MSIs.
The 'entries' argument is a pointer to an array of msix_entry structs
