Add support for "at vp" lookups to namei.  This functionality was added
to HEAD in r185029; but this is an "inspired by" commit rather than a
literal merge, since this region of code in HEAD has other non-MFCable
changes.

The namei lookups this unbreaks are required for ZFS extended attributes;
prior to this commit, an attempt to look up (list, read, write, delete)
extended attributes would be handled as an attempt to look up a file in
the current directory if an extended attribute directory existed ("at vp"
was mishandled as "right here").
