cpuset: fix missing error return in update_cpumask
The commit c6366739804f ("cpuset: refactor cpus_allowed_validate_change")
inadvertently removed the error return when cpus_allowed_validate_change()
fails. This patch restores the proper error handling by returning retval
when the validation check fails.
