MLK-20325: ISI: fix reference count error when camera is not connected

If camera is not connected and user try to use mem2mem function,
driver will return error but isi channel0 reference counter is
still increased by one. This will lead to mem2mem driver return
EBUSY error when user open mem2mem device, so correct this bug
in this patch.
