• Turn the hea and hfa HARP storage pools into UMA zones and insert the necesary uma_zcreate() and uma_zdestroy calls into module loading handler and the device attach handling.
• Change the related HARP netatm code to use UMA zone functions when dealing with the zones that were formerly the ATM interface (hea, hfa) storage pools.
• Have atm_physif_freenifs() now get passed an uma_zone_t so that we can properly free the allocated NIF's back to their zone.

This should be the last commit to remove any code that makes use of the
netatm storage pool api. I will be removing the api code within the near
future.
