rGd1ea07642c47: LinuxKPI: cleanup internal calls to VM_PAGE_TO_PHYS
Summary

Replace FreeBSD native VM_PAGE_TO_PHYS() calls with page_to_phys()
allowing us to work on a struct page in the future using the one
single public Linux KPI interface to map to a native FreeBSD vm_page.

This should be a NOP.

Presumably this will change to kmap(struct page *page) at some point?
