libpayload/xhci: Fix MPS handling in set_address
We set MPS to speed_to_default_mps(speed) initially
but later compare maxpacketsize with 8 to change mps.
So compare with speed_to_default_mps(speed) to determine
if we need to change settings here.
BUG=b:147783572
BRANCH=none
TEST=works with 12Mbps/8MPS USB device
