glsl: Fix overflow of ImageAccess[] array.

The ImageAccess array is statically sized to MAX_IMAGE_UNIFORMS:

   GLenum ImageAccess[MAX_IMAGE_UNIFORMS];

There was no bounds checking ensuring we don't overflow.  Passing in a
shader with too many uniforms would cause writes to extend into other
fields, such as sh->NumImages.

Later linker checks already handle reporting an error when there are too
many images, so just avoid corrupting structures here.

This rearranges the logic a bit to look more like the sampler case.
