This fixes some regressions in i915 when converting to atomic.
set_config failed with -EINVAL, and I received the following warning
in dmesg:
[drm:drm_atomic_crtc_check] [CRTC:20] active without enabled
Solve this by clearing active when a crtc is disabled.
Because crtc_state->enable implies that connectors are active the
change from disabled->enabled can only happen for the crtc that's
being set_config'd, and checking for !crtc_state->enable is sufficient
here.
