Subject: [PATCH 1/4] drv-iio-buffer-*: relocate the .discover method to bring
 the .open and .close methods into scope

To fix #411 [0], the .discover method will now attempt to read from the sensor
buffer. Therefore, it will need to call .open and .close. Relocate the method
to ensure the former are within scope. There is no functional change in the
.discover method.
