Multiple fixed buffer could be used in uring cmd. It's vectored version

There was approximately 10 percent of performance improvements through benchmark.

Applied, thanks!

1-4 look pretty straight forward to me - I'll be happy to queue the
btrfs one as well if the btrfs people are happy with it, just didn't
want to assume anything here.
fwiw, finally got time to wire a hacky test with a separate cmd,
works fine, but I'll need to setup btrfs to test the last patch.
