ocfs2: rewrite error handling of ocfs2_fill_super

[ Upstream commit f1e75d12

 ]

Current ocfs2_fill_super() uses one goto label "read_super_error" to
handle all error cases.  And with previous serial patches, the error
handling should fork more branches to handle different error cases.  This
patch rewrite the error handling of ocfs2_fill_super.
