drm/i915: Fix forcewake active domain tracking
In commit 003342a5 ("drm/i915: Keep track of active forcewake domains in a bitmask") I forgot to adjust the newly introduce fw_domains_active state across reset. This caused the assert_forcewakes_inactive to trigger during suspend and resume if there were user held forcewakes. v2: Bitmask checks are required since vfuncs are not always present. v3: Move bitmask tracking to get/put vfunc for simplicity.
