2013-10-22i40e: fixup legacy interrupt handlingShannon Nelson1-6/+12
There were a number of little bugs in the error handling of irq setup, most of which ended up panicing the kernel, and are addressed by this patch, along with a couple formatting issues. Legacy interrupts (including MSI) are used only in the case of failure to allocate MSI-X interrupts.
