i915/gvt: Fix NULL pointer dereference in init_mmio_block_handlers

Browse source

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: e0f74ed463 ("i915/gvt: Separate the MMIO tracking table from GVT-g")
