George Joseph 9ed0a3c38a channel.c: Don't lock the channel in ast_softhangup while setting rtp instance vars ...

ast_softhangup() was locking the channel before calling ast_rtp_instance_set_stats_vars()
which, if the channel was in a bridge, then locked the bridge peer channel.  If another
thread attempted to set bridge variables on the peer, it would lock that channel first,
then this channel causing a lock inversion.  ast_softhangup() now holds the channel lock
while retrieving the rtp instance, then unlocks it before calling
ast_rtp_instance_set_stats_vars(), then locks it again after it returns.

Resolves: #1907
