ice: Prohibit rx mode change in switchdev mode 



Don't allow to change promisc mode in switchdev mode.
When switchdev is configured, PF netdev is set to be a
default VSI. This is needed for the slow-path to work correctly.
All the unmatched packets will be directed to PF netdev.

It is possible that this setting might be overwritten by
ndo_set_rx_mode. Prevent this by checking if switchdev is
enabled in ice_set_rx_mode.
