Stefan Windfeldt-Prytz f4e23b4343 iio: buffer: check if a buffer has been set up when poll is called 
commit 4cd140bda6 upstream.

If no iio buffer has been set up and poll is called return 0.
Without this check there will be a null pointer dereference when
calling poll on a iio driver without an iio buffer.
