Xue jiufei d1e7823874 ocfs2: do not set OCFS2_LOCK_UPCONVERT_FINISHING if nonblocking lock can not be granted at once ... ocfs2_readpages() use nonblocking flag to avoid page lock inversion. It will trigger cluster hang because that flag OCFS2_LOCK_UPCONVERT_FINISHING is not cleared if nonblocking lock cannot be granted at once. The flag would prevent dc thread from downconverting. So other nodes cannot acheive this lockres for ever. So we should not set OCFS2_LOCK_UPCONVERT_FINISHING when receiving ast if nonblocking lock had already returned.
