commit 64e87d4bd3201bf8a4685083ee4daf5c0d001452 upstream.
domain_add_cpu() is called whenever a CPU is brought online. The earlier call to domain_setup_ctrlval() allocates the control value arrays.
If domain_setup_mon_state() fails, the control value arrays are not freed.
Add the missing kfree() calls.
