uxa: Unmap the buffer after swrast
Otherwise we may exhaust the per-process vma limit and cause
applications to stop rendering and eventually crash the X server.
Will only work in conjunction with a new libdrm (2.4.28) and commit
c549a77c (intel: Unmap buffers during drm_intel_gem_bo_unmap)
in particular.
