Revert "md: improve partition detection in md array"  
  
This reverts commit 5b479c91da90eef605f851508744bfe8269591a0.  
  
Quoth Neil Brown:  
  
"It causes an oops when auto-detecting raid arrays, and it doesn't  
seem easy to fix.  
  
The array may not be 'open' when do_md_run is called, so  
bdev->bd_disk might be NULL, so bd_set_size can oops.  
  
This whole approach of opening an md device before it has been  
assembled just seems to get more and more painful. I think I'm going  
to have to come up with something clever to provide both backward  
comparability with usage expectation, and sane integration into the  
rest of the kernel."
