ice: lag: in RCU, use atomic allocation
Sleeping is not allowed in RCU read-side critical sections.
Use atomic allocations under rcu_read_lock.
Fixes: 1e0f9881ef79 ("ice: Flesh out implementation of support for SRIOV on bonded interface")
Fixes: 41ccedf5ca8f ("ice: implement lag netdev event handler")
Fixes: 3579aa86fb40 ("ice: update reset path for SRIOV LAG support")
