    Move md_update_sb calls
    
    When a change which requires a superblock update happens
    at interrupt time, we currently set a flag (sb_dirty) and
    wakeup to per-array thread (raid1/raid5d/multipathd) to
    do the actual update.
    
    This patch centralises this.  The sb_update is now done
    by the mdrecoveryd thread.  As this is always woken up after
    the error handler is called, we don't need the call to wakeup
    the local thread any more.
    
    With this, we don't need "md_update_sb" to lock the array
    any more and only use __md_update_sb which is local to md.c
    So we rename __md_update_sb back to md_update_sb and stop
    exporting it.
