wctdm24xxp: Fix bug if hook state on FXS changes before channel configuration.
If the hook state on an FXS port changes before the channel is configured with dahdi_cfg it is possible to erroneously force the line feed register open without setting a timer to clear it. The result would be a "dead" channel that cannot be cleared unless the driver is reloaded and warning in the kernel log that "0 is an invalid signaling state for an FXS module". This change makes the OFF_HOOK to ON_HOOK change behave just as the ON_HOOK to OFF_HOOK change has.
