User Query: Cast $user_total as an int.

The `$user_total` member of `WP_User_Query`, and corresponding `get_total()` method, have always been documented as returning an `int`. `$user_total`, however, is populated by `$wpdb->get_var()`, which returns a string (containing an integer value). Casting the return value from `get_var()` as an `int` rectifies this discrepency. Props runciters. Fixes #39297.
