iio: stmpe-adc: Use wait_for_completion_timeout
Use wait_for_completion_timeout instead of
wait_for_completion_interuptible_timeout.
The interruptible variant gets constantly interrupted if a user
program is compiled with the -pg option.
The killable variant was not used due to the fact that a second
program, reading on this device, that gets killed is then also killing
that wait.
