Subject: i40e: Replace spin_is_locked() with lockdep
Patch-mainline: v5.0-rc1
Git-commit: 6a9a5ec10e79425a4df26122705ecf24763b7f2d
References: bsc#1111981 FATE#326312 FATE#326313

lockdep_assert_held() is better suited to checking locking requirements,
since it won't get confused when someone else holds the lock. This is
also a step towards possibly removing spin_is_locked().
