netfs: Fix i_size update for partial transfer

Fix netfs_unbuffered_write_done() to pass the amount written to
netfs_update_i_size() in the event of a partial transfer that ends in an
error.

That said, it might be better for the filesystem to mark the inode data as
invalid and recheck it in case something like a network error occurred that
prevented the reply from the server from being received.
