ocfs2: clean up mount option about atime in ocfs2.txt
As ocfs2 supports relatime and strictatime, we need update the relative document. Atime_quantum need work with strictatime, so only show it in procfs when mount with strictatime. Signed-off-by: Tiger Yang <tiger.yang@oracle.com> Signed-off-by: Joel Becker <jlbec@evilplan.org>
