backlight: ams369fg06: remove redundant variable 'before_power'
'before_power' was used to check the previous status when resume() is
called. However, FB_BLANK_POWERDOWN was used in suspend() all the time,
so there is no need to check the previous status. Also, redundant return
variables are removed to reduce the code.
