inet: shrink struct flowi_common
I am looking at syzbot reports triggering kernel stack overflows
involving a cascade of ipvlan devices.
We can save 8 bytes in struct flowi_common.
This patch alone will not fix the issue, but is a start.
Fixes: 24ba14406c5c ("route: Add multipath_hash in flowi_common to make user-define hash")
