Subject: net: portid signedness and format string fixes

My application blow up as values in nfnetlink_queue suddenly turned
negative.

i.e.
$ cat /proc/net/netfilter/nfnetlink_queue
    0  29508   278 2 65531     0 2004213241 -2129885586  1
    1 -27747     0 2 65531     0     0        0  1
    2 -27748     0 2 65531     0     0        0  1

This series fixes that. Patches 1 to 3 change users of signed
portid to unsigned integers. Just for the sake of consistency.
Patch 4 fixes the printf format string such that applications
don't have to deal with negative numbers.

[PATCH 1/4] netlink: Fix portid type in netlink_notify
[PATCH 2/4] nfc: Fix portid type in urelease_work
[PATCH 3/4] netfilter: Fix portid types
[PATCH 4/4] netfilter: Fix format string of nfnetlink_queue proc file

Thanks,
//richard
