Don't set relatime when noatime is specified
Since commit 0a1c01c9477602ee8b44548a9405b2c1d587b5a2 ("Make relatime
default") when a file system is mounted explicitely with noatime it gets
both the MNT_RELATIME and MNT_NOATIME bits set.
This shows up like this in /proc/mounts:
/dev/xxx /yyy ext3 rw,noatime,relatime,errors=continue,data=writeback 0 0
That looks strange. The VFS uses noatime in this case, but both flags
are set. So it's more a cosmetic issue, but still better to fix.
