net/i40e: fix missing defines for non-AVX build

For non-AVX builds, the cflags used for compiling the i40e driver files
are not passed to the call to build the AVX-specific code path. This can
cause build failures.

../drivers/net/i40e/i40e_ethdev.h:888:42: error: ‘I40E_PFQF_HKEY_MAX_INDEX’ undeclared here (not in a function)

Fixes: e940646b20fa ("drivers/net: build Intel NIC PMDs with meson")
