pipe_upload_constant_buffer0() was immediately releasing the
u_upload_alloc() releasebuf. But it is used in various call-
paths where the release needs to be deferred further.
Fixes crashes in firefox for any driver that uses the same
u_upload_mgr instance for pipe->const_uploader and
pipe->stream_uploader.
Fixes: b3133e250e ("gallium: add pipe_context::resource_release to eliminate buffer refcounting")
