evaluate: bail out if new flowtable does not specify hook and priority
If user forgets to specify the hook and priority and the flowtable does
not exist, then bail out:
# cat flowtable-incomplete.nft
table t {
flowtable f {
devices = { lo }
}
}
# nft -f /tmp/k
flowtable-incomplete.nft:2:12-12: Error: missing hook and priority in flowtable declaration
flowtable f {
^
Update one existing tests/shell to specify a hook and priority.
