[media] s5p-fimc: Fix fimc-lite entities deregistration 

Clear the proper array when deregistering FIMC-LITE devices. Now
fimc[] array is erroneously accessed instead of fimc_lite[] and
fimc_md_unregister_entities() function call can result in an oops
from NULL pointer dereference, since fmd->fimc[] is cleared earlier.
This might happen in normal conditions when the driver's probing
is deferred and then retried.
