passthrough_ll: pass correct errno to fuse_reply_err()
fuse_reply_err() expects the error code, not its negative.
Upstreamed from https://www.redhat.com/archives/virtio-fs/2020-January/msg00000.html. Original commit message:
lo_copy_file_range() passes -errno to fuse_reply_err() and then fuse_reply_err()
changes it to errno again, so that subsequent fuse_send_reply_iov_nofree() catches
the wrong errno.(i.e. reports "fuse: bad error value: ...").
Make fuse_send_reply_iov_nofree() accept the correct -errno by passing errno
directly in lo_copy_file_range().
