Network factory reset: don't recreate VLAN interfaces

This commit fixes a defect with the network factory reset. When VLANs
are created on a particular interface and that interface is reset, the
VLANs should disappear. They weren't disappearing; they were being
deleted and recreated during the reset process. This commit stops the
VLAN interfaces from being recreated.

Resolves openbmc/openbmc#2478
