George Joseph 44aef0449a bridge_channel_write_frame: Check for NULL channel 
There is a possibility, when bridge_channel_write_frame() is
called, that the bridge_channel->chan will be NULL.  The first
thing bridge_channel_write_frame() does though is call
ast_channel_is_multistream() which had no check for a NULL
channel and therefore caused a segfault. Since it's still
possible for bridge_channel_write_frame() to write the frame to
the other channels in the bridge, we don't want to bail before we
call ast_channel_is_multistream() but we can just skip the
multi-channel stuff.  So...

bridge_channel_write_frame() only calls ast_channel_is_multistream()
if bridge_channel->chan is not NULL.

As a safety measure, ast_channel_is_multistream() now returns
false if the supplied channel is NULL.
