rS352176: Replace redundant code with a few new vm_page_grab facilities:
Summary

This is a combination of the below two reviews.

https://reviews.freebsd.org/D21332
https://reviews.freebsd.org/D21331

I eliminated VM_ALLOC_VALID in favor of using VM_ALLOC_NOCREAT with vm_page_grab_valid(). It simplifies things a bit and I think is less ambiguous.
