KVM: Add extra information in kvm_page_fault trace point

KVM: Add extra information in kvm_page_fault trace point

Currently, kvm_page_fault trace point provide fault_address and error
code. However it is not enough to find which cpu and instruction
cause kvm_page_faults. So add vcpu id and instruction pointer in
kvm_page_fault trace point.
