Shaun Ruffell 072ccc9b69 dahdi_echocan_oslec: Call olsec_hpf_tx if CONFIG_DAHDI_PROCESS_ECHOCAN_TX is defined. ...

It can be necessary to have low frequency filter for tx signal of DAHDI.
Otherwise, low-frequency signal from IP can reach a leased line, and
return back with nonlinear distortions. This will break an echo
canceler.
