gallium/radeon: Do not use u_upload_mgr for buffer downloads
Instead create a staging texture with pipe_buffer_create and
PIPE_USAGE_STAGING.
u_upload_mgr sets the usage of its staging buffer to PIPE_USAGE_STREAM.
But since 150ac07b855b5c5f879bf6ce9ca421ccd1a6c938 CPU -> GPU streaming buffers
are created in VRAM. Therefore the staging texture (in VRAM) does not offer any
performance improvements for buffer downloads.
