staging: comedi: remove use of 'bytes_per_sample()'
This inline helper function has been replaced with comedi_bytes_per_sample().
The same commit (bf33eb4b4f57) introduced a couple other related helper
functions a manipulate the sample size.
Use the new helper functions to remove the use of 'bytes_per_sample()' and
remove it.
