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: e30d1756480dc ("[SCSI] qla2xxx: Addition of shutdown callback handler.")
