libpayload: ehci: Fix byte count in dump_td()

Browse source 
The dump_td() debug function in the EHCI stack incorrectly masks the
amount of transferred bytes on output... the actual field is 15 bits
wide (30:16). Let's just use the mask constant we already have for all
the other code.

BUG=None
TEST=None
