Fix following coccicheck error:
./drivers/gpu/drm/i915/gvt/handlers.c:2925:35-41: ERROR: block is NULL but dereferenced.
Use gvt->mmio.mmio_block instead of block to avoid NULL pointer
dereference when find_mmio_block returns NULL.
Fixes: e0f74ed4634d ("i915/gvt: Separate the MMIO tracking table from GVT-g")
