Subject: [PATCH iproute2-next] ip-address: Fix negative prints of large TX rate limits

TX rate limit fields are unsigned (__u32).
Print them using %u.

Tested:
$ ip link set ens1 vf 1 rate 2294967296
$ ip link show |grep -iE "vf 1" | grep rate

before:
vf 1 MAC 00:00:00:00:00:00, tx rate -2000000000 (Mbps), max_tx_rate -2000000000Mbps, ...

after:
vf 1 MAC 00:00:00:00:00:00, tx rate 2294967296 (Mbps), max_tx_rate 2294967296Mbps, ...

Fixes: 3fd86630876a ("iproute2: rework SR-IOV VF support")
Fixes: 8c29ae7cc249 ("ip link: Fix crash on older kernels when show VF dev")
Fixes: f89a2a05ffa9 ("Add support to configure SR-IOV VF minimum and maximum Tx rate through ip tool")
Fixes: ae7229d5f99e ("ip: Add support for setting and showing SR-IOV virtual funtion link params")
Fixes: d0e720111aad ("ip: ipaddress.c: add support for json output")
