scsi: ufs: core: Convert a comment into an explicit check

The comment /* UFSHCD_QUIRK_REINIT_AFTER_MAX_GEAR_SWITCH is set */ is
only correct if ufshcd_device_init() is only called by
ufshcd_probe_hba().  Convert the comment into an explicit check. This
patch prepares for moving the ufshcd_device_init() calls.
