kernel: netfilter: nf_set_pipapo: fix initial map fill

A buffer overflow vulnerability exists in the Linux kernel. After each round in the map search step, the result and the fill map are swapped. If a set where f-bsize of the first element is smaller than m-bsizemax, those one-bits are leaked into future rounds result map, resulting in loss of syste...
