[PATCH v2] net/ice: fix secondary process Rx offload path

Secondary process depends on the vector offload flag to select right
Rx offload path. This patch adds a variable in share memory to store
the vector offload flag that can be directly read by secondary process.
Fixes: 808a17b3c1e6 ("net/ice: add Rx AVX512 offload path")
