[spice-gtk PATCH v1 2/3] webdav: small cleanups

[Victor Toso <victortoso@xxxxxxxxxx>]

changes:
- unecessary return on demux_to_client;
- client struct has reference to current SpiceWebdavChannel so it can be
  removed as parameter in client functions;
- using gboolean parameter to check if demux_to_client_finish failed
  will be useful in the next commit
