Summary:                    [patch] zap hookstate is never set offhook if wctdm
module is loaded with an active fxo line
Description: 
If #define ZAP_CHECK_HOOKSTATE is uncommented in chan_zap.c, then the
hookstate stays onhook if the wctdm module is loaded with an active line. 
Removing line and reinserting will cause the hookstate to initialize
properly.  The problem appears to be that wc->mod[card].fxo.battery never
gets initialized to 0, so in wctdm_voicedaa_check_hook() the test "if
(!wc->mod[card].fxo.battery && !wc->mod[card].fxo.battdebounce)" is never
entered, and the hookstate remains onhook upon module startup.  Only a
cycling of line voltage will correct the problem.  I have attached a patch
which initializes the battery variable and fixes the problem for me.

Not if ZAP_CHECK_HOOKSTATE is defined.  In that case it is supposed to
actually check the state of the line.  Which works, but the problem was the
hookstate was always the same when the module loads, and required cycling
the line (unplug and plug back in) to pick up the hookstate.
