[PATCH] md: merge md_enter_safemode into md_check_recovery
md_enter_safemode checks if it is time to mark the md superblock as 'clean'.
i.e. if all writes have completed and a suitable delay has passed.
This is currently called from md_handle_safemode which in-turn is called
(almost) every time md_check_recovery is called, and from the end of
md_do_sync which causes the mddev->thread to run, which will always call
md_check_recovery as well.
So it doesn't need to be a separate function and fits quite well into
md_check_recovery.
The "almost" is because multipathd calls md_check_recovery but not
md_handle_safemode. This is OK because the code from md_enter_safemode is a
no-op if mddev->safemode == 0, which it always is for a multipathd (providing
we don't allow it to be set to 2 on a signal...)
