Summary:                    oops after removing an echocan module that is in use
Description: 
1. Start a system as usual (with Asterisk and with channels that have echo
cancelers).

2. rmmod dahdi_echocan_<whatever>

3. cat /proc/dahdi/*

4. oops

The module is used by other modules. And yet we don't keep proper
reference counting.
