netfs: Delete some xarray-wangling functions that aren't used

Delete some xarray-based buffer wangling functions that are intended for
use with bounce buffering, but aren't used because bounce-buffering got
deferred to a later patch series.  Now, however, the intention is to use
something other than an xarray to do this.
