CPU: Avoid using unititialized error variable in disable_nonboot_cpus()
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. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
