iio: backend: print message in case op is not implemented

Browse source

For APIs that have a return value, -EOPNOTSUPP is returned in case the
backend does not support the functionality. However, for APIs that do
not have a return value we are left in silence. Hence, at least print a
debug message in case the callback is not implemented by the backend.
