staging: comedi: don't dereference user memory for INSN_INTTRIG

Browse source

`parse_insn()` is dereferencing the user-space pointer `insn->data`
directly when handling the `INSN_INTTRIG` comedi instruction.  It
shouldn't be using `insn->data` at all; it should be using the separate
`data` pointer passed to the function.  Fix it.
