rtnetlink: add RTEXT_FILTER_NAME_ONLY support to rtnl_dump_ifinfo()
When user requests RTEXT_FILTER_NAME_ONLY flag, we limit the dump
parts to:
- struct nlmsghdr
- IFLA_IFNAME
- IFLA_PROP_LIST (alternate names)
- This saves space in the dump, pushing more devices per system call.
- This can be done without acquiring RTNL.
I still have a medium term goal to avoid RTNL in rtnl_dump_ifinfo()
regardless of RTEXT_FILTER_NAME_ONLY being used.
