dahdi: Drivers that do not support hwec should not report hwec is available.
When attaching software echocans to a channel, if there is a hardware
echocan available always give preference to them.
Revision 9995 "dahdi: Always attach hwec to a channel if available" had
an error where if a driver did not even support an option of hardware
echocan, dahdi-base would take that to mean there always was a hardware
echocan available on the channel.
