[PATCH] hfs: set correct create date for links
HFS+ also requires the correct creation date so recent version of OS X
recognize it as link.
Improve link handling:
- if something is wrong with the link, ignore the link attribute and treat
it as regular file (this also fixes a missing unlock during lookup).
- check for incorrect link counts during unlink.
