drm/i915: Fix HAS_REGION() usage in intel_gt_probe_lmem()

HAS_REGION() takes a bitmask, not the region ID. This causes the
GEM_BUG_ON() to assert that the SMEM region is available rather
than the intended LMEM region. No real harm since SMEM is always
available, but also not checking what was intended.
