David Howells 4058f74210 netfs: Keep track of the actual remote file size ...

Provide a place in which to keep track of the actual remote file size in
the netfs context.  This is needed because inode->i_size will be updated as
we buffer writes in the pagecache, but the server file size won't get
updated until we flush them back.
