[PATCH] drivers/misc/apds9802als.c: fix runtime PM errors

[Hong Liu <hong.liu@xxxxxxxxx>]

Putting the device into runtime suspend after resume()/probe() is handled
by the PM core and the device core code. No need to manually add them in
each single driver. And correct the runtime state in remove().
