Change subject: app_confbridge: Only use b_profile options from the conference.
......................................................................
app_confbridge: Only use b_profile options from the conference.
A user cannot set new bridge options after the conference is created by
the first user. Attempting to do so is documented as undefined behavior.
This patch ensures that the bridge profile options used are from the
conference and not what a subsequent user may have tried to set.
