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...
