[PATCH][next] drm/i915: fix uninitialized variable 'mask'

[Colin King]

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

Currently mask is not initialized and so data is being bit-wise or'd into
a garbage value. Fix this by inintializing mask to zero.

Addresses-Coverity: ("Uninitialized scalar variable")
Fixes: 1ac159e23c2c ("drm/i915: Expand subslice mask")
