address hfs on-disk corruption robustness review comments
Address Roman's review comments for the previously sent on-disk
corruption hfs robustness patch.
- use 0 as a failure value, rather than making a new macro HFS_BAD_KEYLEN,
and use a switch statement instead of if's.
- Add new fail: target to __hfs_brec_find to skip assignments using bad
values when exiting with a failure.
