Revert "ibmvnic: remove duplicate napi_schedule call in open function"

This reverts commit 7c451f3ef676c805a4b77a743a01a5c21a250a73.

When a vnic interface is taken down and then up, connectivity is not
restored. We bisected it to this commit. Reverting this commit until
we can fully investigate the issue/benefit of the change.
