[PATCH v2] net: not build PMD AVX library when no IOVA as PA

[Qi Zhang]

PMD not announce pmd_supports_disable_iova_as_pa will not be build
when RTE_IOVA_AS_PA is not defined, but some AVX library for vector
path is not skipped by the build system which cause compile error.

The patch modify i40e, iavf, ice's meson file to skip AVX library
build when RTE_IOVA_AS_PA is not defined.
