uas: fix super speed bMaxPacketSize0
For usb2 bMaxPacketSize0 is "n", for usb3 it is "1 << n",
so it must be 9 not 64 ...
rom "Universal Serial Bus 3.1 Specification":
If the device is operating at Gen X speed, the bMaxPacketSize0
field shall be set to 09H indicating a 512-byte maximum packet.
An Enhanced SuperSpeed device shall not support any other maximum
packet sizes for the default control pipe (endpoint 0) control
endpoint.
We now announce a 512-byte maximum packet.
