net/dpdk: ix build with 13-CURRENT

The automated package builds for net/dpdk are failing on 13-CURRENT
because of changes to the FreeBSD code in the 13 tree. This update
provides minor tweaks to the code to fix compatibility with BSD 13.

Two issues were observed:

• rename of CPU_NAND to CPU_ANDNOT
• change in vm_page_replace parameters and behaviour

Both issues only required small changes to a single file, and both
fixes are in the diff attached.
