xhci: change 'msix_count' to encompass MSI or MSI-X vectors

Browse source

Instead of variable 'msix_count' containing the number of MSI-X vectors,
now it can contains MSI or MSI-X vector amount. Because both interrupt
methods allow several vectors. Thus, 'msix_count' is renamed to 'nvecs'.

Additionally, instead of storing the maximum possible vector amount,
now it stores the amount of successfully allocated vectors, or negative
integer on allocation failure.
