usb: usbtest: fix the bit mask of usb 2.0 extension descriptor

USB 2.1 Link PM adds to use bits[1:15] according to USB 2.0 ECN Errata for
Link Power Management spec.

Bit Encoding
0 Reserved
1 LPM
2 BESL & Altemate HIRD definitions supported
3 Recommended Baseline BESL valid
4 Recommended Deep BESL valid
11:8 Recommended Baseline BESL value
15:12 Recommended Deep BESL value
31:16 Reserved

So fix the bit mask from 0x1e to 0xfffe.
