As USB_DT_USB_SSP_CAP_SIZE() takes SSAC value as an argument, the low
bound of the size for struct usb_ssp_cap_descriptor should be described
by USB_DT_USB_SSP_CAP_SIZE(0), not by USB_DT_USB_SSP_CAP_SIZE(1)
The type-specific length check patch was added to stable and needs to be
fixed as well.
Fixes: 81cf4a45360f ("USB: core: Add type-specific length check of BOS
descriptors")
