cluster/afr: Check before accessing xattrs in data self heal.
The lookup xattrs might be null, because a lookup might not have been issued during self heal, especially if only data self heal is required. Signed-off-by: Pavan Vilas Sondur <pavan@gluster.com> Signed-off-by: Anand V. Avati <avati@dev.gluster.com> BUG: 815 (quick-read and replicate self-heal interaction result in empty reads) URL: http://bugs.gluster.com/cgi-bin/bugzilla3/show_bug.cgi?id=815
