====================
net: ipa: little fixes

This series adds a few small fixes to the IPA code.

The first patch appeared in a different form in June, and got some
pushback from David because he felt a problem that can be caught at
build time *should* be caught at build time.

I agree with that, but in this case the "problem" was never actually
a problem.  There's a little more explanation on the patch, but
basically now we remove the BUILD_BUG_ON() call entirely.

The second deletes a line of code that isn't needed.

The third converts a warning message to be a debug, as requested by
Stephen Boyd.

And the last one just gets rid of an error message that would be
output after a different message had already reported a problem.
