x86, mm: put mmu-to-h/w ASID translation in one place
We effectively have two ASID types:
1. The one stored in the mmu_context that goes from 0->5
2. The one we program into the hardware that goes from 1->6
Let's just put the +1 in a single place which gives us a
nice place to comment. KAISER will also need to, given an
ASID, know which hardware ASID to flush for the userspace
mapping.
