Merge branch 'mlx4-fixes'

Tariq Toukan says:

====================
mlx4 bug fixes for 4.9

This patchset includes 2 bug fixes:
* In patch 1 we revert the commit that avoids invoking unregister_netdev
in shutdown flow, as it introduces netdev presence issues where
it can be accessed unsafely by ndo operations during the flow.
* Patch 2 is a simple fix for a variable uninitialization issue.
