drm/i915: Don't leak edid in intel_crt_detect_ddc()
commit c34f078675f505c4437919bb1897b1351f16a050 upstream.
In the path where intel_crt_detect_ddc() detects a CRT, if would return
true without freeing the edid.
Fixes: a2bd1f541f19 ("drm/i915: check whether we actually received an edid in detect_ddc")
