ice: Prevent set_channel from changing queues while RDMA active

The PF controls the set of queues that the RDMA auxiliary_driver requests
resources from.  The set_channel command will alter that pool and trigger a
reconfiguration of the VSI, which breaks RDMA functionality.

Prevent set_channel from executing when RDMA driver bound to auxiliary
device.

Adding a locked variable to pass down the call chain to avoid double
locking the device_lock.
