Subject: [net-next 1/9] i40e: mark PM functions as __maybe_unused

From: Arnd Bergmann <arnd@...db.de>

A cleanup of the PM code left an incorrect #ifdef in place, leading
to a harmless build warning:

drivers/net/ethernet/intel/i40e/i40e_main.c:12223:12: error: 'i40e_resume' defined but not used [-Werror=unused-function]
drivers/net/ethernet/intel/i40e/i40e_main.c:12185:12: error: 'i40e_suspend' defined but not used [-Werror=unused-function]

It's easier to use __maybe_unused attributes here, since you
can't pick the wrong one.

Fixes: 0e5d3da40055 ("i40e: use newer generic PM support instead of legacy PM callbacks")
