xen,pod: Only sweep in an emergency, and only for 4k pages
Testing has shown that doing sweeps for superpages slows down boot
significantly, but does not result in a significantly higher number of
superpages after boot. Early sweeping for 4k pages causes superpages
to be broken up unnecessarily.
Only sweep if we're really out of memory.
v2:
- Move unrelated code-motion hunk to another patch
v3:
- Remove now-unused reclaim_super from pod struct
