Stefan Assmann 52285b762b igb: release already assigned MSI-X interrupts if setup fails 
During MSI-X setup the system might run out of vectors. If this happens the
already assigned vectors for this NIC should be freed before trying the
disable MSI-X. Failing to do so results in the following oops.

kernel BUG at drivers/pci/msi.c:341!
