net: ipa: use WARN_ON() rather than assertions
I've added commented assertions to record certain properties that
can be assumed to hold in certain places in the IPA code. Convert
these into real WARN_ON() calls so the assertions are actually
checked, using the standard WARN_ON() mechanism.
Where errors can be returned, return an error if a warning is
triggered.
