From: Joseph Qi <joseph.qi@xxxxxxxxxx>
Subject: ocfs2: add the missing return value check of ocfs2_xattr_get_clusters
In ocfs2_xattr_value_attach_refcount(), if error occurs when calling
ocfs2_xattr_get_clusters(), it will go with unexpected behavior since
local variables p_cluster, num_clusters and ext_flags are declared without
initialization.
