Hide USB errors better from the upper layers: Only try the "clear feature"
command if the error is B_DEV_STALLED. On other errors, the clear feature
was likely to fail, as it should only be used on stalled devices. Errors
intended to be ignored were thus not ignored because of the "clear feature"
failure.
