It was impossible to enumerate on a SuperSpeed (XHCI) host
with alternate setting = 1 due to the wrongly set 'bMaxBurst'
field in the SuperSpeed Endpoint Companion descriptor.
Testcase:
<host> modprobe -r usbtest; modprobe usbtest alt=1
<device> modprobe g_zero
plug device to SuperSpeed port on the host.
Without this patch the host always complains like so
"usb 12-2: Not enough bandwidth for new device state.
usb 12-2: Not enough bandwidth for altsetting 1"
Bug was introduced by commit cf9a08ae in v3.9
