scsi: ufs: core: Do not hold any lock in ufshcd_hba_stop()
This change is motivated by Bart's suggestion in [1], which enables to
further reduce the SCSI host lock usage in the UFS driver. The reason why
it makes sense, because although the legacy interrupt is disabled by some
but not all ufshcd_hba_stop() callers, it is safe to nest disable_irq()
calls as it checks the irq depth.
