Don't backport 757b000f7b93 ("timekeeping: Fix possible inconsistencies in _COARSE clockids")

Hi!

It turned out that this commit causes a regression for adjtimex() users, so it will be reverted in mainline.

There is a different fix available which does not have that problem, which will be marked with a Fixes tag and will be suitable for backporting.

Thanks,
