KVM: VMX: Reorder clearing of registers in the vCPU-run assembly flow
Move the clearing of the common registers (not 64-bit-only) to the start
of the flow that clears registers holding guest state. This is
purely a cosmetic change so that the label doesn't point at a blank line
and a #define.
No functional change intended.
