ocfs2: fix some small problems
First, move setting fe_done = 1 in spin lock, avoid bring any potential race condition. Second, tune mlog message level from ERROR to NOTICE, since the message should not belong to error message. Third, tune errno to -EAGAIN when file check queue is full, this errno is more appropriate in the case.
