drm/edid: Dump the EDID when drm_edid_get_panel_id() has an error
If we fail to get a valid panel ID in drm_edid_get_panel_id() we'd
like to see the EDID that was read so we have a chance of
understanding what's wrong. There's already a function for that, so
let's call it in the error case.
NOTE: edid_block_read() has a retry loop in it, so actually we'll only
print the block read back from the final attempt. This still seems
better than nothing.
