cluster/afr : Examine data/metadata readable for read-subvol
During lookup and discover, currently read_subvol is based
only on data_readable. read_subvol should be decided based
on both data_readable and metadata_readable.
Credits to Ravishankar N for the logic of afr_first_up_child
from http://review.gluster.org/10905/ .
