icount: update instruction counter on apic patching
kvmvapic patches the code when some instructions are executed. E.g. mov 0xff, 0xfffe0080 is interpreted as push 0xff/call ... This patching is also followed by some side effects (changing apic and guest memory state). Therefore deterministic execution should take this operation into account. This patch decreases icount when original mov instruction is trying to execute. Therefore patching becomes deterministic and can be replayed correctly.
