[PATCH 29/36] staging: comedi: ni_tio: make ni_tio_winsn() a proper comedi (*insn_write)

[H Hartley Sweeten]

Change the parameters to ni_tio_winsn() to make it a proper comedi
(*insn_write) function. This allows using it directly and removing the
wrapper functions in the ni_660x and ni_mio_common modules.

For aesthetics, rename the function.
