      reload Chan_dahdi memory leak caused by variables

      chan_dahdi reloading with variables set via setvar in chan_dahdi.conf would
      stay in the dahdi_pvt structs for individual channels (causing them to just
      continue adding the new ones to the list) and also there was a memory leak
      causes by the conf objects. This patch resolves both of these by using 
      ast_variables_destroy during the loading process.
