    ext4: Add fallback for find_group_flex
    
    This is a workaround for find_group_flex() which badly needs to be
    replaced.  One of its problems (besides ignoring the Orlov algorithm)
    is that it is a bit hyperactive about returning failure under
    suspicious circumstances.  This can lead to spurious ENOSPC failures.
    Work around this for now by retrying the search using
    find_group_other() if find_group_flex() returns -1.  If
    find_group_other() succeeds when find_group_flex(), log a warning
    message.  I can't quite find the motivation to spend effort working on
    fixing find_group_flex() given that I want to replace it all anyway
    (and in fact work on the replacement code is underway), so we may
    leave the workaround for as long as find_group_flex() stays in the
    kernel...

XXX ERS: Remove printk, it's too much noise now, we got the bug reports
