scsi: lpfc: fix pci hot plug crash in timer management routines
commit 1901762f2ca2747ed269239ca5332a8023ce4e3d upstream.
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.
