sys/vfs/hammer: Add comments on ip localization of @@PFS symlink
- The userspace hammer command shows "You are attempting to access
a PFS softlink from a PFS..." and exit(1) whenever one tries to
make a PFS from non root fs directory.
- This restriction by userspace ensures @@PFS symlinks always belong
to the root fs, in other words ip localization of those symlinks
are always 0. HAMMER's kernel code doesn't impose this restriction
on pfs, but userspace does.
