staging: comedi: ni_pcidio: use comedi_buf_write_samples()
Use comedi_buf_write_samples() to add the sample to the async buffer. The 32-bit
sample size is automatically determined due to the subddev_flag SDF_LSAMPL.
The async event COMEDI_CB_BLOCK will be automatically set by the core. Remove the
unnecessary event in the driver.
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.
