st/mesa: fix invalid pointer use in st_texture_get_sampler_view()
The '**used' pointer was pointing into the stObj->sampler_views array. If 'free' was null, we'd realloc that array, thus making the 'used' pointer invalid. This soon led to memory errors. Just change the pointer to be '*used' so it points directly at the pipe_sampler_view. Reviewed-by: Michel Dänzer <[email protected]>
