scsi: ufs: Uninitialized variable in ufshcd_devfreq_target()

There is one goto where "sched_clk_scaling_suspend_work" is true but
"scale_up" is uninitialized.  It leads to a Smatch uninitialized variable
warning:

drivers/ufs/core/ufshcd.c:1589 ufshcd_devfreq_target() error: uninitialized symbol 'scale_up'.
