[PATCH nft] rule: allow src/dstnat prios in input and output

[PATCH nft] rule: allow src/dstnat prios in input and output

[Florian Westphal]

Dan Winship says:

The "dnat" command is usable from either "prerouting" or "output", but the
"dstnat" priority is only usable from "prerouting". (Likewise, "snat" is usable
from either "postrouting" or "input", but "srcnat" is only usable from
"postrouting".)

No need to restrict those priorities to pre/postrouting.
