[RFC 4/4] devtools: demote tag ordering to warning

[Stephen Hemminger <stephen@networkplumber.org>]

The Linux kernel does not enforce a strict tag ordering via tooling.
Ordering is a convention, enforced socially by maintainers rather
than by checkpatch.pl.  The b4 tool has a configurable trailer-order
preference, but it is not mandatory.

Demote the tag ordering check from an error (which sets failure=true
and causes a non-zero exit) to a warning (printed but does not
affect the exit code).  This avoids rejecting patches that are
otherwise correct but happen to have Reviewed-by before Acked-by
or similar minor ordering differences.
