This is a handful of simple cleanups which I made
while investigating
https://bugs.passt.top/show_bug.cgi?id=41. Note that these don't
themselves actually address that bug, they're just unrelated cleanups
that happen to be in adjacent code.
I've run basic tests on these, but not quite the complete test suite:
I haven't yet had a chance to debug an unrelated problem with the IPv4
performance tests failing.
Changes since v1:
* Minor comment and style fixes
