Check whether to call the driver.unthrottle function.
We test the TTY_THROTTLED bit first so that it always
indicates the current state. The decision about whether
it is worth allowing more input has been taken by the caller.
Can sleep, may be called under the atomic_read semaphore but
this is not guaranteed.
