  - Only set i_offset in the parent directory's i-node during a lookup for
    non-LOOKUP operations.
  - Relax a VOP assertion for a DELETE lookup.  rename() uses WANTPARENT
    instead of LOCKPARENT when looking up the source pathname.  ufs_rename()
    uses a relookup() to lock the parent directory when it decides to finally
    remove the source path.  Thus, it is ok for a DELETE with WANTPARENT set
    instead of LOCKPARENT to use a shared vnode lock rather than an exclusive
    vnode lock.
