staging: comedi: fix return value for insn_bits functions
The comedi_subdevice 'insn_bits' functions return the number of data
elements used to perform the command. Most of the insn_bits functions
return an open coded '2' to indicate this. The same value is available
as 'insn->n'. Return that instead to better indicate what the return
means.
