iio: fix drivers that check buffer->scan_mask
If the in-kernel push interface is used we may have a different masks
on the device buffer and the kernel buffer and in this case the device
should generate data for the reunion of the buffers, which is
available at indio_dev->active_scan_mask.
Compiled tested only except for bmc150-accel which was tested at
runtime with the hardware.
