Kirk McKusick efe145a745 Correct assert added to dump program. 
The dump program was exiting with the message:

Assertion failed: (spcl.c_count + blks < TP_NINDIR), function appendextdata, file /usr/src/sbin/dump/traverse.c, line 759.

The problem arose when dumping external attributes.

This assertion was added in this commit with no review by someone
with expertise in the dump program:

    commit 2d518c6518

	Add asserts to prevent overflows of c_addr.

It is clearly wrong as the statement immediately above it in the
code which is deciding if the data will fit is:

	if (spcl.c_count + blks > TP_NINDIR)
		return (0);

As is pointed out in the bug report, the assert should be:

	(spcl.c_count + blks <= TP_NINDIR)

This commit corrects the assert. I am sorry that it took so long to
be brought to my attention and get fixed.
