Subject: [PATCH] x86/resctrl: Free the ctrlval arrays when
domain_setup_mon_state() fails

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.
