Merge #152268

152268: storage: inline `recordStats` function in `linux_parse.go` to fix lint r=dodeca12 a=dodeca12

`./dev lint` runs a series of lint checks, which includes `TestLint/TestStaticCheck`; `TestLint/TestStaticCheck` throws an an error:
```log
=== RUN   TestLint/TestStaticCheck
    gen-lint_test.go:2119:
        pkg/storage/disk/monitor.go:198:25: func (*monitoredDisk).recordStats is unused (U1000)
```

However, `recordStats` is used in `pkg/storage/disk/linux_parse.go` which has a `//go:build linux` constraint, so it is actually not "unused". 

This PR resolves the linter error by inlining the behaviour in `linux_parse.go` and removing the function from `monitor.go`.

Epic: None
Release note: None
