drm/xe: Wait on bookkeep dma-resv slots when unmapping / mapping same address
There is a window between unmap and map of the same address in which the
old and new address is invalid. Avoid this window by waiting bookkeep
dma-resv when unmapping and mapping the same address.
This race is shown when running xe_vm.mmap* on presi platform which by
nature are more susceptible to races.
Fixes: ("drm/xe: Convert multiple bind ops into single job")
