This adds support for daemons who preregister buffers to minimize the overhead
of pinning/unpinning user pages and translating virtual addresses. Registered
buffers pay the cost once during registration then reuse the pre-pinned pages,
which helps reduce the per-op overhead.
This is on top of commit 211ddde0823f in the iouring tree.
