This reverts commit 45c3d213a400c952ab7119f394c5293bb6877e6b.
lima driver need preclose to wait all task in the context created within closing file to finish before free all the buffer object. Otherwise pending tesk may fail and get noisy MMU fault message.
Move this wait to each buffer object free function can achieve the same result but some buffer object is shared with other file context, but we only want to wait the closing file context's tasks. So the implementation is not that straight forword compared to the preclose one.
You should just separate your MMU structures from drm_file, and have drm_file and the jobs using it keep a reference on them. This is what I've done in V3D as well.
