_libssh2_channel_close: don't call transport read if disconnected

Browse Source 
The loop that waits for remote.close to get set may end up looping
forever since session->socket_state gets set to
LIBSSH2_SOCKET_DISCONNECTED by the packet_add() function called from the
transport_read() function and after having been set to
LIBSSH2_SOCKET_DISCONNECTED, the transport_read() function will only
return 0.
