staging: comedi: make some variables unsigned in comedi_write()
In `comedi_write()`, the `n` and `m` variables are of type `int`.
Change them to `unsigned int` as they are used to measure a positive
number of bytes. The `count` variable is also of type `int` and holds
the returned number of bytes written. Change it to type `ssize_t` to
match the function's return type.
