modules/app_lua: Fix to lua_sr_pv_is_null()

- Previously this function returned an error when it could not retrieve the pv
  (for example if it did not exist).  As Lua is not a language in which you
  have to declare variables not existing is equivalent to NULL.  This function
  now treats a pv that does not exist as NULL.
