staging: comedi: fix infoleak to userspace

commit 819cbb120eaec7e014e5abd029260db1ca8c5735 upstream.

driver_name and board_name are pointers to strings, not buffers of size
COMEDI_NAMELEN.  Copying COMEDI_NAMELEN bytes of a string containing
less than COMEDI_NAMELEN-1 bytes would leak some unrelated bytes.
