drivers/media/video/msm/ledflash.c: Fix Test Sysfs Entries

I think this might be a step closer?
we now have a entry /sys/kernel/ledflash/flashonoff
If the value of flashonoff = 1 it turns "on" the flash if 0 it turns it "off". If the flash has been set "on" elsewhere the value is set to 1 if its been set to "off" value is set to 0. 
Assuming that what i wrote works and does what i think it will.(lol)
