x86: fix oprofile double free
Chuck reports that the recent fix from Andi to oprofile
6c977aad03a18019015035958c65b6729cd0574c introduces a double free. Each
cpu's cpu_msrs is setup to point to cpu 0's, which causes free_msrs to free
cpu 0's pointers for_each_possible_cpu. Rather than copy the pointers, do
a deep copy instead.
[[email protected]: allocate_msrs() was using for_each_online_cpu()]
