Christoph Hellwig bbcacab2e8 brd: avoid extra xarray lookups on first write ...

The xarray can return the previous entry at a location.  Use this
fact to simplify the brd code when there is no existing page at
a location.  This also slighly improves the handling of racy
discards as we now always have a page under RCU protection by the
time we are ready to copy the data.
