From: Dick Kennedy <dick.kenn...@broadcom.com>
During pci hot plug, the kernel crashes in timer management code.
The sli4 remove_one handler is not stoping the timers as it starts to
remove the port so that it can be swapped.
Fix: Stop the timers early in the handler routine.
Note: Fix in SLI-4 only. SLI-3 already stopped the timers properly.
