x86/mm: Refactor possibly deadlocking get_gfn calls
When calling get_gfn multiple times on different gfn's in the same function, we
can easily deadlock if p2m lookups are locked. Thus, refactor these calls to
enforce simple deadlock-avoidance rules:
- Lowest-numbered domain first
- Lowest-numbered gfn first
