drm_hwcomposer: Fix protected layer hole punch
The old code didn't dereference the layer index from the
bitmask which caused it to subtract layers it shouldn't
have. In order to do this right, we need to look at the
layer index corresponding to the bit in the id_set to
ensure we're excluding the correct layers.
BUG=None
TEST=Precomposition doesn't draw over dedicated layers
