[Spice-devel] [PATCH spice-gtk 2/7] channel: check if channel has a session

[Marc-André Lureau]

Since 8943d2329, the channel may be disconnected from the session
before it's destroyed. In this case, session is NULL.

Fixes some critical with virt-manager when closing a display:

(virt-manager:20451): GSpice-CRITICAL **: spice_session_is_for_migration: assertion 'SPICE_IS_SESSION(session)' failed
