internal/fuzz: don't deflake coverage found while fuzzing Previously, the worker would attempt to deflake an input that was reported to have caused new coverage. The chances of a flake causing new coverage seem pretty low to me, and even if it was a flake that caused it, adding that input to the cache doesn't seem like a bad thing. The input is already going to be deflaked during minimization anyway. If by some off-chance the code is causing a lot of flaky coverage increases, and the user doesn't want minimization to occur, then setting -fuzzminimizetime=1x will deflake in the way they want without minimizing. This can be documented as needed. This fixes a bug where the mem.header().count could have been one too large if an unrecoverable crash occured while deflaking an input that caused code coverage.
