CPU: Avoid using unititialized error variable in disable_nonboot_cpus()

Browse Source 
If there's only one CPU online when disable_nonboot_cpus() is called,
the error variable will not be initialized and that may lead to
erroneous behavior.  Fix this issue by initializing error in
disable_nonboot_cpus() as appropriate.
