Subject: afr: Splitbrain with size as policy must not resolve for directory

In automatic Splitbrain resolution when favorite child policy
is set as size, split brain resolution must not work for
directories.

Currently, if a directory is in split brain with both copies
having same size, the source is selected arbitrarily
and healed.

fixes: bz#1655050
