usb: xhci: request MSI/-X according to requested amount

Variable 'max_interrupters' contains the maximum supported interrupters
or the maximum interrupters the user has requested. Thus, it should be
used instead of HCS_MAX_INTRS().

User set 'max_interrupters' value is validated in xhci_gen_setup(),
otherwise 'max_interrupters' value is 'HCS_MAX_INTRS(xhci->hcs_params1)'.
