vppinfra: Fix bihash del warning

Type: fix When freeing an uninstantiated bihash created with dont_add_to_all_bihash_list = 1 we get a warning. This removes the warning & the search for the bihash on cleanup. Change-Id: Iac50ce7e30b97925768f7ad3cb1d30af14686e21 Signed-off-by: Nathan Skrzypczak <nathan.skrzypczak@gmail.com>
