drm/amd/display: refresh cached HDMI FreeSync state
When an HDMI sink re-reports an EDID without an AMD VSDB,
get_amd_vsdb() returns false but the connector's cached vsdb_info was
previously updated only on success. A previous FreeSync-capable EDID could
therefore leave freesync_supported set and keep selecting the FreeSync SPD
path instead of the HDMI VRR VTEM path.
Refresh the cached VSDB record for every HDMI EDID update so a missing AMD
VSDB clears stale FreeSync state. Keep the existing SPD/VTEM packet
separation and protocol-selection logic unchanged.
Fixes: 123e9515f7e0 ("drm/amd/display: Send HDMI VRR metadata in VTEM info packet slot")
