Fix OperatorValidator for floating-point (non-deterministic) opcodes

[camilbancioiu]

This pull request fixes an inverted if in check_non_deterministic_enabled(), which was allowing floating-point opcodes even when deterministic_only was set to true.

Also renames check_non_deterministic_enabled() to check_deterministic_only(), to make it clearer.

On the master branch, Cargo.toml defines the deterministic feature, which seems to be enabled during the CI tests (is it?). The test which parses the file float_memory.0.wasm doesn't expect an error, and fails with the fixed OperatorValidator. Is the test correct?

It is defined, but not enabled (as default features)

The test is correct.

@yurydelendik Thank you for your quick reply. I'll look deeper into this, it might be an issue somewhere else (we're using Wasmer, which in turn relies on Wasmparser).
