Merge branch 'devlink-prepare-mlxsw-and-netdevsim-for-locked-reload'

Jiri Pirko says:

====================
devlink: prepare mlxsw and netdevsim for locked reload

This is preparation patchset to be able to eventually make a switch and
make reload cmd to take devlink->lock as the other commands do.

This patchset is preparing 2 major users of devlink API - mlxsw and
netdevsim. The sets of functions are similar, therefore taking care of
both here.
