Due to a horrible omission in the big IRQ list traversal, all movable IRQs
are misattributed to the last active CPU in the system since that's what
`bd` is last set to in the loop prior. This horribly breaks SBalance's
notion of balance, producing nonsensical balancing decisions and failing to
balance IRQs even when they are heavily imbalanced.
Fix the massive breakage by adding the missing line of code to set `bd` to
the CPU an IRQ actually belongs to, so that it's added to the correct CPU's
movable IRQs list.
