[Asterisk-code-review] bridge softmix.c: Change remove destination streams() return... (asterisk[master])

[Jenkins2]

Jenkins2 has submitted this change and it was merged. ( https://gerrit.asterisk.org/7646 )

Change subject: bridge_softmix.c: Change remove_destination_streams() return meaning.
......................................................................

bridge_softmix.c: Change remove_destination_streams() return meaning.

The return value of remove_destination_streams() now means we removed a
stream from the topology by making it a dead stream.  Now we won't try to
request a topology change if we didn't remove any streams.
