Recent changes to the devlink reload (commit 9b2348e2


("devlink: warn about existing entities during reload-reinit"))
force the drivers to destroy devlink ports during reinit.
Adjust ice driver to this requirement, unregister netdvice, destroy
devlink port. ice_init_eth() was removed and all the common code
between probe and reload was moved to ice_load().

During devlink reload we can't take devl_lock (it's already taken)
and in ice_probe() we have to lock it. Use devl_* variant of the API
which does not acquire and release devl_lock. Guard ice_load()
with devl_lock only in case of probe.
