libmount: revert "read mtab on remount" idea
It's backwardly incompatible nonsense to prefer mtab on remount.
mount -o remount /foo
has to read mount options from fstab otherwise the remount has no
effect. (The ideal solution would be to read both mtab, then modify
the options according to fstab -- but for now more important is to be
backwardly compatible.)
