  To: helin.zhang, konstantin.ananyev; +Cc: dev, Stephen Hemminger

Run ixgbe driver through checkpatch and edit away all the
nasty bits.  Fix line spacing, some bad indentation, and in a couple
of cases use short circuit (already there) return to lessen indentation.

v2 - fix more things found by checkpatch
