ocfs2: Don't repeat ocfs2_xattr_block_find()
ocfs2_xattr_block_get() looks up the xattr in a startlingly familiar way; it's identical to the function ocfs2_xattr_block_find(). Let's just use the later in the former. Signed-off-by: Joel Becker <joel.becker@oracle.com> Signed-off-by: Mark Fasheh <mfasheh@suse.com>
