[PATCH nft] netlink: delinearize: copy set keytype if needed

[Florian Westphal <fw@strlen.de>]

Output before:
add @dynmark { 0xa020304 [invalid type] timeout 1s : 0x00000002 } comment "also check timeout-gc"

after:
add @dynmark { 10.2.3.4 timeout 1s : 0x00000002 } comment "also check timeout-gc"

This is a followup to 76c358ccfea0 ("src: maps: update data expression dtype based on set"),
which did fix the map expression, but not the key.

 Found with an unrelated test case, i will submit that one as well soon.
