x86, setup: When probing memory with e801, use ax/bx as a pair
When we use BIOS function e801 to probe memory, we should use ax/bx
(or cx/dx) as a pair, not mix and match. This was a typo during the
translation from assembly code, and breaks at least one set of
machines in the field (which return cx = dx = 0).
