iio: industrialio-buffer: Fix iio_buffer_poll return value

Browse source

commit 1bdc029390 upstream.

Change return value to 0 if no device is bound since
unsigned int cannot support negative error codes.

Fixes: f18e7a068 ("iio: Return -ENODEV for file operations if the
device has been unregistered")
