staging: comedi: rearrange comedi_write() code
Rearrange the code in `comedi_write()` to reduce the amount of indentation. The code never reiterates the `while` loop once `count` has become non-zero, so we can check that in the `while` condition to save an indentation level. (Note that `nbytes` has been checked to be non-zero before entering the loop, so we can remove that check.) Move the code that makes the subdevice "become non-busy" outside the `while` loop, using a new flag variable `become_nonbusy` to decide whether it needs to be done. This simplifies the wait queue handling so there is a single place where the task is removed from the wait queue, and we can remove the `on_wait_queue` flag variable.
