e backlight - avoid seg when comp is shut down and backlight updated 

if comp is already shut down, then backlight can't do shutdown things
assuming comp is around, thus handle null e_comp. this fixes segv's
waiting to happen as backlight is shut down after comp and thus e_comp
is a garbage pointer of course

@fix
