target-i386: Reorganize TSC rate setting code
Following changes are made to the TSC rate setting code in
kvm_arch_init_vcpu():
* The code is moved to a new function kvm_arch_set_tsc_khz().
* If kvm_arch_set_tsc_khz() fails, i.e. following two conditions are
both satisfied:
* KVM does not support the TSC scaling or it fails to set vcpu's
TSC rate by KVM_SET_TSC_KHZ,
* the TSC rate to be set is different than the value currently used
by KVM, then kvm_arch_init_vcpu() will fail. Prevously,
* the lack of TSC scaling never failed kvm_arch_init_vcpu(),
* the failure of KVM_SET_TSC_KHZ failed kvm_arch_init_vcpu()
unconditionally, even though the TSC rate to be set is identical
to the value currently used by KVM.
