Current MSI-X enablement code assumes MSI-Xs were successfully
allocated in case less than requested vectors were available.
That assumption is wrong, since MSI-Xs should be enabled with
a repeated call to pci_enable_msix(). This update fixes this.

and pci_msix_table_size() for MSI-X.
More complex cases would entail matching device capabilities
with the system environment, i.e. limiting number of hardware
queues (and hence associated MSI/MSI-X interrupts) to the number
of online CPUs.
