[PATCH] insane: Clean up horrible return value processing code

[Richard Purdie <richard.purdie@linuxfoundation.org>]

Whilst in theory return values are nice, handling the complex aggregation
of the return values is ugly. The code already uses QA_SANE as a marker
to signal problems. Whilst that isn't as idealistic, it makes the code
massively cleaner, so rely on this instead.
