From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
Currently subslice_mask is not initialized and so data is being
bit-wise or'd into a garbage value. Fix this by inintializing
subslice_mask to zero.
Addresses-Coverity: ("Uninitialized scalar variable")
Fixes: 1ac159e23c2c ("drm/i915: Expand subslice mask")
