mlx4_core: Initialize ctx_list and ctx_lock earlier
We may call mlx4_dispatch_event() before mlx4_register_device() is
called for a device, because for example a catastrophic error happens
immediately after we enable interrupts. Therefore priv->ctx_list and
priv->ctx_lock need to be initialized earlier.
This bug was actually exposed by the MSI-X bug that returned IRQ numbers
to drivers in reverse order, so that the first FW command
interrupt looked to mlx4 like a catastrophic error.
