Junxiao BiandGreg Kroah-Hartman 88ec9bbcd3 Revert "md/raid5: Wait for MD_SB_CHANGE_PENDING in raid5d" ...

[ Upstream commit bed9e27baf ]

This reverts commit 5e2cf333b7.

That commit introduced the following race and can cause system hung.

 md_write_start:             raid5d:
 // mddev->in_sync == 1
 set "MD_SB_CHANGE_PENDING"
                            // running before md_write_start wakeup it
                             waiting "MD_SB_CHANGE_PENDING" cleared
                             >>>>>>>>> hung
 wakeup mddev->thread
 ...
 waiting "MD_SB_CHANGE_PENDING" cleared
 >>>> hung, raid5d should clear this flag
 but get hung by same flag.

The issue reverted commit fixing is fixed by last patch in a new way.
