ocfs2: Remove EXIT from masklog.
mlog_exit is used to record the exit status of a function. But because it is added in so many functions, if we enable it, the system logs get filled up quickly and cause too much I/O. So actually no one can open it for a production system or even for a test. This patch just try to remove it or change it. So: 1. if all the error paths already use mlog_errno, it is just removed. Otherwise, it will be replaced by mlog_errno. 2. if it is used to print some return value, it is replaced with mlog(0,...). mlog_exit_ptr is changed to mlog(0. All those mlog(0,...) will be replaced with trace events later. Signed-off-by: Tao Ma <boyu.mt@taobao.com>
