[PATCH 07/44] KVM: x86: Do timer initialization after XCR0 configuration

Move kvm_arch_init()'s call to kvm_timer_init() down a few lines below
the XCR0 configuration code. A future patch will move hardware setup
into kvm_arch_init() and slot in vendor hardware setup before the call
to kvm_timer_init() so that timer initialization (among other stuff)
doesn't need to be unwound if vendor setup fails. XCR0 setup on the
other hand needs to happen before vendor hardware setup.
