Log Message:
Pull up following revision(s) (requested by msaitoh in ticket #490):
        sys/dev/pci/ixgbe/ixgbe.c: revision 1.116-1.119
        sys/dev/pci/ixgbe/ixv.c: revision 1.76-1.77
Don't panic when resource shortage occured. Fixes PR#52820 reported by
kardel@:
 - Don't use if_free() because ixgbe(4) don't use if_alloc().
 - Move location of {ixgbe,ixv}_setup_interface() call at a position that
   any error don't occur. One of the reason is that it should be. Another
   reason is that it's hard to call ether_ifdetach() and if_detach() when
   cold == 1 (because of pserialize_perform, xc_wait, timing of domaininit
   and maybe more).

Don't panic when resource shortage occured. Like ixgbe.c rev. 1.116.

--
Fix panic when only link interrupt can't be established.
--
- If MSI can't be used on some environment, fallback to INTx correctly.
- Use single vector MSI when number of CPU is 1 to save interrupt slot.
--
Fallback from MSI-X to MSI or INTx if MSI-X setup failed.
