ice: Block switchdev mode when ADQ is active and vice versa

Browse source

[ Upstream commit 43d00e102d ]

ADQ and switchdev are not supported simultaneously. Enabling both at the
same time can result in nullptr dereference.

To prevent this, check if ADQ is active when changing devlink mode to
switchdev mode, and check if switchdev is active when enabling ADQ.
