dri: Use designated initializers for DRI extension structs

The dri directory is compiled with -std=c99. There is no excuse to not use
designated initializers.

As a nice benefit, the code is now more friendly to grep. Without
designated initializers, psychic prowess is required to find the
initialization of DRI extension function pointers with grep.  I have
observed several people, when they first encounter the DRI code, fail at
statically chasing the DRI function pointers due to this problem.
