go1.18 breaks govet nilness and unusedwrite

[nvx]

Welcome

• Yes, I'm using a binary release within 2 latest major releases. Only such installations are supported.
• Yes, I've searched similar issues on GitHub and didn't find any.
• Yes, I've included all information below (version, config, etc).
• Yes, I've tried with the standalone linter if available. (https://golangci-lint.run/usage/linters/)

Description of the problem

govet nilness and unusedwrite linters break with go1.18.

Uncommenting the disable lines in the example config provided fixes the issue. These should be disabled when go: 1.18 is specified in the config file like other problematic linters.

Hello, it's already in #2438 and #2649.

As it's not directly related to golangci-lint, I close this issue.

FYI I opened an issue on the Go repo golang/go#51038 that has been flag as a duplicate of golang/go#48525

[ldez]

The 2 analyzers will be inactivated with go1.18, take a look at #2669

yup sweet, that was what I was hoping for

anything beyond that is obviously out of scope of golangci-lint
