Chris Redpath 2e14ecb254 sched: HMP: fix potential logical errors

The previous API for hmp_up_migration reset the destination
CPU every time, regardless of if a migration was desired. The code
using it assumed that the value would not be changed unless
a migration was required. In one rare circumstance, this could
have lead to a task migrating to a little CPU at the wrong time.

Fixing that lead to a slight logical tweak to make the surrounding
APIs operate a bit more obviously.
