mlxsw: spectrum: Add missing rollbacks in error path

idosch · davem330 · commit 0583272d91f0 · 2016-08-17T19:18:27.000-04:00
While going over the code I noticed we are missing two rollbacks in the port's creation error path. Add them and adjust the place of one of them in the port's removal sequence so that both are symmetric.
