Pursuant to r360398, implement driver-specific versions of the ifdi_needs_restart iflib device method. Some (if not most?) Intel network cards don't need reinitializing when a VLAN is added or removed from the device hardware, so these implement ifdi_needs_restart in a way that tell iflib not to bring the interface up or down when a VLAN is added or removed, regardless of whether the VLAN_HWFILTER interface capability flag is set or not. This could potentially solve several PRs relating to link flaps that occur when VLANs are added/removed to devices.
