Fix the suspend path by ensuring the rtnl lock is held where required.
Calls to open, close and WOL operations must be performed under the
rtnl lock to prevent conflicts with ongoing ndo operations.

While working on the ravb fix, it was discovered that the sh_eth driver
has the same issue. This patch series addresses both drivers.

I do not have access to hardware for either of these MACs, so it would
be great if maintainers or others with the relevant boards could test
these fixes.
