[sr-dev] git:4.2:b41d779b: websocket: Check frame->wsc in ws_frame_transmit for NULL.

Module: kamailio Branch: 4.2 Commit: b41d779b6d8b30f311a490d76f211c1ca656ce38 URL: https://github.com/kamailio/kamailio/commit/b41d779b6d8b30f311a490d76f211c1… Author: Walter Doekes <walter+github(a)wjd.nu> Committer: Daniel-Constantin Mierla <miconda(a)gmail.com> Date: 2015-01-15T20:13:01+01:00 websocket: Check frame->wsc in ws_frame_transmit for NULL. Add frame.wsc == NULL check in ws_frame_transmit similar to the checks in ws_close and friends and ws_frame_receive to avoid crashing if the tcp connection was been terminated prematurely.
