Maciej Żenczykowski reported lockdep warning a spinlock
was not registered before being held in mlx4_cmd_wake_completions()
cmd.context_lock initialization is not at the right place.
1) mlx4_cmd_use_events() can be called multiple times.
Calling spin_lock_init() on a live spinlock can lead
to hangs.
2) mlx4_cmd_wake_completions() can be called while lock
has not been initialized.
Lockdep complains, and current logic is not race prone.
It seems better to move the initialization earlier in
mlx4_load_one()
