There is an option `RTE_PMD_PACKET_PREFETCH` in `rte_config.h` that is
always set to 1 by default, and that controls some prefetch behavior in the
driver. However, there's another prefetch behavior that is controlled by
`RTE_PMD_USE_PREFETCH`, which is always defined unconditionally (literally
using `#if 1` construct).

Replace the check to also use `RTE_PMD_PACKET_PREFETCH` to allow turning it
off at build time.
