SetFontPath: set client->errorValue on failure.

Backported from X.org: commit 21ceae9002c6364deb3d074cf2da7d3864cf6879 Author: Jamey Sharp <jamey@minilop.net> Date: Tue May 11 10:24:00 2010 -0700 SetFontPath: set client->errorValue on failure. Previously the callers were only setting errorValue on Success, when it's ignored, and leaving it alone on failure, when it's sent to the client. Since SetFontPath takes the ClientPtr, let it set client->errorValue instead of letting the callers continue to get it wrong.
