io_uring: Remove redundant hrtimer's callback function setup
The IORING_OP_TIMEOUT command uses hrtimer underneath. The timer's callback
function is setup in io_timeout(), and then the callback function is setup
again when the timer is rearmed.
Since the callback function is the same for both cases, the latter setup is
redundant, therefore remove it.
