      Dereference before null check

      There may be a null reference exception, or else the comparison against null is unnecessary. All paths that lead to this null pointer comparison already dereference the pointer earlier
      /src/MongoDB.Driver/Linq/Linq3Implementation/Ast/Expressions/AstMapExpression.cs:55: REVERSE_INULL 127277 Directly dereferencing "this._as".
      /src/MongoDB.Driver/Linq/Linq3Implementation/Ast/Expressions/AstMapExpression.cs:55: REVERSE_INULL 127277 Null-checking "this._as" suggests that it may be null, but it has already been dereferenced on all paths leading to the check.
