Buggy rankings in config bitnum=all

[doegox]

There is one single PriorityQueue no matter which bit is used, so in the configuration bitnum=all, ranking for the last target bits contain previous results.

E.g. testing wbs_aes_hacklu2009/DCA/addr8_r_20_5888.config in attack mode with:

bitnum=7
bytenum=0
#correct_key=0x14 2b be 0e 2d 22 e4 80 97 49 7d 5f ac 5b 59 26

gives
