[SR-Users] define-check for dlg_var doesn't work

[Daniel-Constantin Mierla]

Hello,

from the code, I see that if the value does not exists, the get-function 
for dlg_var is just returning 0. Probably it should return PV null value.

Try again after changing return 0 in return pv_get_null(...) inside 
function pv_get_dlg_variable(...) from dlg_var.c

If works, you can commit the fix.

Cheers,
Daniel
