Jens Axboe 8ec680e4c3 ioprio: allow sys_ioprio_set() value of 0 to reset ioprio setting ...

Normally io priorities follow the CPU nice, unless a specific scheduling
class has been set. Once that is set, there's no way to reset the
behaviour to 'none' so that it follows CPU nice again.

Currently passing in 0 as the ioprio class/value will return -1/EINVAL,
change that to allow resetting of a set scheduling class.
