[patch] drm/edid: fix a debug message

[Dan Carpenter]

There is an extra semi-colon on the if statement so the debug output
always says "Failed to write EDID checksum" even when it didn't fail.

Fixes: 559be30cb74d ('drm/i915: Implement the intel_dp_autotest_edid function 
for DP EDID complaince tests')
