[dpdk-dev] [PATCH 1/6] build: fix for FREEBSD build via meson

[Agalya Babu RadhaKrishnan <agalyax.babu.radhakrishnan@intel.com>]

FreeBSD compilation was failing through meson build.
RTE_EAL_VFIO is not supported in FreeBSD.
But RTE_EAL_VFIO was enabled for both linux and freebsd.
So RTE_EAL_VFIO is removed from config/rte_config.h and
based on the platform RTE_EAL_VFIO flag is enabled/disabled appropriately.

Fixes: 6e8a721044 ("vfio: export functions even when disabled")
