Commit e086ba2fccda ("e1000e: disable s0ix entry and exit flows for ME
systems") added e1000e_check_me() but it's only called from
CONFIG_PM_SLEEP protected code. Thus builds without CONFIG_PM_SLEEP
see:
drivers/net/ethernet/intel/e1000e/netdev.c:137:13: warning: 'e1000e_check_me'
defined but not used [-Wunused-function]
Add CONFIG_PM_SLEEP ifdef guard to avoid dead code.
Fixes: e086ba2fccda ("e1000e: disable s0ix entry and exit flows for ME systems")
