[Intel-wired-lan] [PATCH net-next] ice: fix ethtool set channel when in switchdev mode

[Marcin Szycik <marcin.szycik@intel.com>]

From: Grzegorz Nitka <grzegorz.nitka@intel.com>

When running ethtool set channel (-L) command on PF interface,
DCB reconfiguration is triggered which in turn involves TC
re-configuration and ring to vector mapping. It applies to
all VSI instances, regardles of VSI type, so also including
switchdev ctrl VSI when device is running in switchdev mode.

Skip ring to vector mapping for switchdev ctrl VSI, as it
uses non-standard mapping and is already properly configured
when PF VSI is rebuilt.
