====================
net: ipa: kill IPA_VALIDATION

A few months ago I proposed cleaning up some code that validates
certain things conditionally, arguing that doing so once is enough,
thus doing so always should not be necessary.

Leon Romanovsky felt strongly that this was a mistake, and in the
end I agreed to change my plans.

This series finally completes what I said I would do about this,
ultimately eliminating the IPA_VALIDATION symbol and conditional
code entirely.

The first patch both extends and simplifies some validation done for
IPA immediate commands, and performs those tests unconditionally.

The second patch fixes a bug that wasn't normally exposed because of
the conditional compilation (a reason Leon was right about this).
It makes filter and routing table validation occur unconditionally.

The third eliminates the remaining conditionally-defined code and
removes the line in the Makefile used to enable validation.

And the fourth removes all comments containing ipa_assert()
statements, replacing most of them with WARN_ON() calls.
