Summary: schedule_delivery calls ast_bridged_channel() on an
unlocked channel
Description:
Near the beginning of schedule_delivery(), ast_bridged_channel() is called
on iaxs[fr->callno]->owner; however, that channel is not locked, which can
result in ast_bridged_channel() crashing should owner->tech change to a
technology that doesn't implement bridged_channel. I spoke with briefly
with russellb on IRC who agreed that this usage is unsafe.
