mesa/uniform_query: Don't write to *params if there is an error

The GL 3.1 and ES 3.0 specs say of glGetActiveUniformsiv:
   "If an error occurs, nothing will be written to params."

So, make a pass through the indices and check that they're valid before
the pass that actually writes to params. Checking pname happens on the
first iteration of the second loop.

Fixes es3conform's getactiveuniformsiv_for_nonexistent_uniform_indices
test.

NOTE: This is a candidate for the 9.0 branch.
