rtnetlink: call validate_linkmsg in rtnl_create_link
commit
b0ad3c179059089d809b477a1d445c1183a7b8fe upstream.
validate_linkmsg() was introduced by commit
1840bb13c22f5b ("[RTNL]:
Validate hardware and broadcast address attribute for RTM_NEWLINK")
to validate tb[IFLA_ADDRESS/BROADCAST] for existing links. The same
check should also be done for newly created links.
This patch adds validate_linkmsg() call in rtnl_create_link(), to
avoid the invalid address set when creating some devices like:
# ip link add dummy0 type dummy
# ip link add link dummy0 name mac0 address 01:02 type macsec
