Chris Wright 0939c17c7b x86: fix oprofile double free 
Chuck reports that the recent fix from Andi to oprofile
6c977aad03 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.

[acme@redhat.com: allocate_msrs() was using for_each_online_cpu()]
