igb: mark PM functions as __maybe_unused
The new wake function is only used by the suspend/resume handlers that
are defined in inside of an #ifdef, which can cause this harmless
warning:
drivers/net/ethernet/intel/igb/igb_main.c:7988:13: warning: 'igb_deliver_wake_packet' defined but not used [-Wunused-function]
Removing the #ifdef, instead using a __maybe_unused annotation
simplifies the code and avoids the warning.
Fixes: b90fa87635
("igb: Enable reading of wake up packet")
