Removed the ``#if 0'' that turned bounds_check_with_label() into worse

than a NOP.  bounds_check_with_label() would return -1 yet NOT set any
of the bio flags to show an error.  This meant the caller would not
properly see that bounds_check_with_label() did not do any work.  This
prevented newfs(8) from being able to write a file system on any partition
other than `c' on a `ccd'.

The logs of this file do not tell _why_ bounds_check_with_label() was
emasculated.  Nor are there any `XXX' comments.  So we'll unemasculated
it, and see what breaks.
