hellofromTonya 5584cf60c0 REST API: Remove 'Invalid user ID' error in WP_REST_Users_Controller::update_item().
Removes the `WP_Error` code for `'Invalid user ID.'`. Why?

tl;dr
This branch will never be entered as the `$user` will never be falsey.

Longer reasoning:

[39954] introduced `WP_REST_Users_Controller::get_user()` method to encapsulate getting the user and handling the `'Invalid user ID.'` `WP_Error`. It replaced `get_userdata()` in `WP_REST_Users_Controller::update_item()` but left the existing `'Invalid user ID.'` `WP_Error` introduced in [38832].

The code removed in this changeset will never be reached because `$user` will never be falsey. Rather, `WP_REST_Users_Controller::get_user()` will always return an instance of `WP_Error` or `WP_User`. 

Could the user's ID be falsey?
No. Why? `WP_REST_Users_Controller::get_user()` checks that the user exists, which checks if the ID is falsey.

Therefore, the code can safely be removed.

Follow-up to [39954], [38832].
