md: revert io stats accounting
commit ad3fc798800fb7ca04c1dfc439dba946818048d8 upstream.
The commit 41d2d848e5c0 ("md: improve io stats accounting") could cause
double fault problem per the report [1], and also it is not correct to
change ->bi_end_io if md don't own it, so let's revert it.
And io stats accounting will be replemented in later commits.
