st/mesa: only memset sampler when about to use it.

This function was taking a lot more CPU than required due to it memsetting
a bunch of memory that didn't require it from what I can see.

We should only memset here when we are about to fill out the sampler,
otherwise we end up doing a bunch of memsets for everytime this function
is called, basically setting 0 memory to 0.
