x86: Use online node real index in calulate_tbl_offset()
Found a NUMA system that doesn't have RAM installed at the first
socket which hangs while executing init scripts.
bisected it to:

| x86: Spread tlb flush vector between nodes
It turns out when first socket is not online it could have cpus on
node1 tlb_offset set to bigger than NUM_INVALIDATE_TLB_VECTORS.
That could affect systems like 4 sockets, but socket 2 doesn't
have installed, sockets 3 will get too big tlb_offset.
Need to use real online node idx.
