gssd: fix crash in debug message.

A recent cleanup of debug messages added func and tid format specifiers
to a debug message (when full hostname was different), but the func name
and tid were NOT added as arguments.

Consequently there weren't enough args, random bytes of the stack were
interpreted as a pointer, and rpc.gssd crashed (when -v was specified).
