usb: typec: ucsi: allow non-partner GET_PDOS for Qualcomm devices

Browse Source 
The name and description of the USB_NO_PARTNER_PDOS quirk specifies that
only retrieving PDOS of the attached device is crashing. Retrieving PDOS
of the UCSI device works. Fix the condition to limit the workaround only
to is_partner cases.
