Summary:                    implicit declaration of function 'module_refcount'
when building dahdi
Description: 
When building dahdi-linux 2.1.0.4 a user received the following error

/usr/src/asterisk/1.6/dahdi-linux-2.1.0.4/drivers/dahdi/xpp/xproto.c: In
function 'xproto_get':
/usr/src/asterisk/1.6/dahdi-linux-2.1.0.4/drivers/dahdi/xpp/xproto.c:96:
error: implicit declaration of function 'module_refcount'
make[3]: ***


This was since his kernel did not define CONFIG_MODULE_UNLOAD and
module_refcount is only defined when CONFIG_MODULE_UNLOAD is defined.

Fix building Zaptel with module unloading disabled

As moduel_refcount is only used for debugging, disable it in this
non-common case.
