Revert "gallium/u_threaded: buffer sharedness tracking"
This reverts commit 8f159a85.
This commit is correct but it exposes an existing bug: DISCARD_RANGE doesn't work well with shared buffers. So for now revert this commit as it's causing hangs on some APUs (see drm/amd#2447 (closed)) and flickering in Metro Last Light Redux.
Closes: #9108 (closed)
