iio: sx9500: Use complete() instead of complete_all()
There is only one waiter for the completion, therefore there
is no need to use complete_all(). Let's make that clear by
using complete() instead of complete_all().
The usage pattern of the completion is:
waiter context waker context
sx9500_read_proximity()
sx9500_inc_chan_users()
sx9500_inc_data_rdy_users()
wait_for_completion_interruptible()
s9500_irq_thread_handler()
complete()
reinit_completion()
