The dev->read_subdev used in this driver for async commands returns 32-bit samples
and should have the SDF_LSAMPL subdev_flag set. It also returns the full scan with
each sample so it should have the SDF_PACKED subdev_flag set.

Add the missing subdev_flags and use comedi_buf_write_samples() to add the sample
to the async buffer.

Use comedi_buf_write_samples() to add the sample to the async buffer. The 32-bit

The async event COMEDI_CB_BLOCK will be automatically set by the core. Remove the

This driver also has the SDF_PACKED subdev_flag set so the core will automatically
set the COMEDI_CB_EOS event after adding the sample.

Change the return type of move_block_from_dma() to void and remove the
unnecessary check of the return value of comedi_buf_write_samples().
The callers don't check the return and it's really not necessary. If
comedi_buf_write_samples() fails to allocate enough space in the async
buffer to add all the samples it sets the COMEDI_CB_OVERFLOW event.
