* The complaint in ztest_replay_write() is only possible if something
went horribly wrong. An assertion will silence this and if it goes
off, we will know that something is wrong.
* The complaint in spa_estimate_metaslabs_to_flush() is not impossible,
but seems very unlikely. We resolve this by passing the value from
the `MIN()` that does not go to infinity when the variable is zero.
There was a third report from Clang's scan-build, but that was a
definite false positive and disappeared when checked again through
Clang's static analyzer with Z3 refution via CodeChecker.
