[PATCH 40/55] staging: comedi: pcl816: use comedi_buf_write_samples()

[H Hartley Sweeten]

For aesthetics, use comedi_buf_write_samples() to add the sample to the
async buffer.

The core will add the COMEDI_CB_BLOCK event when data is written to the
async buffer. Remove the unnecessary event in the driver.
