cluster/afr: Unable to self heal symbolic links
Problem:
Under the entry self heal, readlink is done at the
source and sink. When readlink is done at the sink,
because link is not present at the sink, afr expects
ENOENT. AFR translator takes decisions for new link
creation based on ENOENT but server translator is modified
to return ESTALE because of which afr xlator is not able
to heal.
Fix:
The check for inode absence at server includes ESTALE as
well.
