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.
