Do not call 'ima_path_check()' for each path component
Not only is that a supremely timing-critical path, but it's hopefully
some day going to be lockless for the common case, and ima can't do
that.
Plus the integrity code doesn't even care about non-regular files, so it
was always a total waste of time and effort.
