uas: ignore UAS for Thinkplus chips
commit 0fb9703a3eade0bb84c635705d9c795345e55053 upstream.
The UAS mode of Thinkplus(0x17ef, 0x3899) is reported to influence
performance and trigger kernel panic on several platforms with the
following error message:
[ 39.702439] xhci_hcd 0000:0c:00.3: ERROR Transfer event for disabled
endpoint or incorrect stream ring

Falling back to USB mass storage can solve this problem, so ignore UAS
function of this chip.
