errors from rn_inithead back to the ipfw initialization function. - Check return value of rn_inithead for failure, if table allocation has failed for any reason, free up any tables we have created and return ENOMEM - In ipfw_init check the return value of init_tables and free up any mutexes or UMA zones which may have been created. - Assert that the supplied table is not NULL before attempting to dereference. This fixes panics which were a result of invalid memory accesses due to failed table allocation. This is an issue mainly because the R_Zalloc function is a malloc(M_NOWAIT) wrapper, thus making it possible for allocations to fail.
