[PATCH v2 2/3] vhost: : remove fallbacks for old Linux versions

[Bruce Richardson <bruce.richardson@intel.com>]

All supported linux versions support F_ADD_SEALS (Linux 3.17+) and
MFD_HUGETLB (Linux 4.14+), so no need to have #ifdefs and fallbacks to
support systems which do not support those features.
