netfs: Fix READ/WRITE confusion when calling iov_iter_xarray()
Fix netfs_clear_unread() to pass READ to iov_iter_xarray() instead of WRITE
(the flag is about the operation accessing the buffer, not what sort of
access it is doing to the buffer).
Fixes: 3d3c95046742 ("netfs: Provide readahead and readpage netfs helpers")
