It constructs a clear feature request for the endpoint halt selector
and sends the request using debug transfers. Clearing a stall condition
can be done safely and has one nice side effect: it reinitializes the
data toggle to a known state. This command can therefore be used when
a pipe is possibly used from userland as well and the data toggle may
therefore be out of sync.
