Xin Long 8ac106aade rtnetlink: call validate_linkmsg in rtnl_create_link 
[ Upstream commit b0ad3c1790 ]

validate_linkmsg() was introduced by commit 1840bb13c2 ("[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

Fixes: 0e06877c6f ("[RTNETLINK]: rtnl_link: allow specifying initial device address")
