Fix infoleak to userspace.

Following Vasiliy Kulikov <segoon _at_ openwall _dot_ org>'s patch for
the staging sources:

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.
