[hawkingrei]

What problem does this PR solve?

Issue Number: close #40786

Problem Summary:

What is changed and how it works?

In Go it is idiomatic to minimize nesting statements, a typical example is to avoid if-then-else constructions. This rule spots constructions like

if cond {
  // do something
} else {
  // do other thing
  return ...
}

where the if condition may be inverted in order to reduce nesting:

if !cond {
  // do other thing
  return ...
}
