ice: Prevent set_channel from changing queues while RDMA active
[ Upstream commit
a6a0974aae4209d039ba81226ded5246eea14961 ]
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.
