At a bare minimum, this function will return 0 if a BE is mounted at the given path or non-zero otherwise. If the optional 'details' nvlist is supplied, it is filled with an nvpair containing just the information about the BE mounted at the path. This nvpair is structured just as it is for be_get_bootenv_props, except limited to just the single mount point.
