I'm seeing warnings on kernel configurations where CONFIG_PM is
disabled.  It happens in 4.12, at least:

drivers/ethernet/intel/igb/igb_main.c:7988:13: warning: 'igb_deliver_wake_packet' defined but not used [-Wunused-function]

This is because igb_deliver_wake_packet() is defined outside of
the #ifdef", but is used only a single time within the #ifdef in
igb_resume().  Fix it by moving igb_deliver_wake_packet() next to
igb_resume() inside the #ifdef.

The diff ends up looking a bit funky here.  It *looks* like
igb_suspend() is getting moved, but that's an artifact of how
'diff' sees the changes.

I'll let Jeff queue this up into his tree.
