[PATCH] KVM: SVM,VMX: Use %rip-relative addressing to access kvm_rebooting

[Uros Bizjak]

Instruction with %rip-relative address operand is one byte shorter than
its absolute address counterpart and is also compatible with position
independent executable (-fpie) build.

No functional changes intended.
