Subject: [PATCH] ixgbed: fix pci_allocate_interrupt_vector method call to free
 function

Commit 717bc436 introduced MSI-X support via
pci_allocate_interrupt_vector but called it as a method on
PciFunction (.pci_allocate_interrupt_vector(1)), which doesn't
exist. The function is actually a free function in
pcid_interface::irq_helpers, matching the pattern used by e1000d,
rtl8139d, rtl8139d, and ihdad.

Fix: add the import and change the call to match e1000d's pattern:
  pci_allocate_interrupt_vector(&mut pcid_handle, "ixgbed")

This unblocks the base cook for all targets.
