scsi: qla2xxx: stop timer in shutdown path

[ Upstream commit d3566abb1a1e7772116e4d50fb6a58d19c9802e5 ]

In shutdown/reboot paths, the timer is not stopped:

  qla2x00_shutdown
  pci_device_shutdown
  device_shutdown
  kernel_restart_prepare
  kernel_restart
  sys_reboot

This causes lockups (on powerpc) when firmware config space access calls
are interrupted by smp_send_stop later in reboot.

Fixes: e30d175648 ("[SCSI] qla2xxx: Addition of shutdown callback handler.")
