====================
octeon_ep: fixes for error and remove paths

I have an Octeon card that's misconfigured in a way that exposes a
couple of bugs in the octeon_ep driver's error paths. It can reproduce
the issues that patches 1 & 4 are fixing. Patches 2 & 3 are a result of
reviewing the nearby code.
