dri: Clarify comments on InfoMessageF and ErrorMessageF macros.

The description of ErrorMessageF was misleading in the case of
LIBGL_DEBUG being unset, (the previous comment could be understood to
mean the error should be printed, but the code does not print in this
case).

InfoMessageF previously had no comment at all.
