xfsprogs: inode-related repair fixes [v30.9 05/28]

While doing QA of the online fsck code, I made a few observations:
First, nobody was checking that the di_onlink field is actually zero;
Second, that allocating a temporary file for repairs can fail (and
thus bring down the entire fs) if the inode cluster is corrupt; and
Third, that file link counts do not pin at ~0U to prevent integer
overflows.

This scattered patchset fixes those three problems.

This has been running on the djcloud for months with no problems.  Enjoy!
