[Bug 90537] radeonsi bo/va conflict on RADEON_GEM_VA (rscreen->ws->buffer_from_handle returns NULL)

https://bugs.freedesktop.org/show_bug.cgi?id=90537

--- Comment #4 from Christian König deathsimple@vodafone.de --- Watch out for memory leaks as well.

When mesa drops the last reference to the BO by closing it's handle the VA mapping should go away automatically. That's the reason why it works for X and EGL.

What you see here is that you manually need to remove the VA mapping because there is still a reference to the BO outside of mesa.

Could be intentional, but could be a bug as well.

Anyway Michels patch is clearly a good idea.
