RDMA/netdev: Hoist alloc_netdev_mqs out of the driver
netdev has several interfaces that expect to call alloc_netdev_mqs from
the core code, with the driver only providing the arguments. This is
incompatible with the rdma_netdev interface that returns the netdev
directly.
Thus re-organize the API used by ipoib so that the verbs core code calls
alloc_netdev_mqs for the driver. This is done by allowing the drivers to
provide the allocation parameters via a 'get_params' callback and then
initializing an allocated netdev as a second step.
Fixes: cd565b4b51e5 ("IB/IPoIB: Support acceleration options callbacks")
