x86: Stop manually clearing RFLAGS.RF after a system call. The system call stub KVM uses in SE mode to call the system call pseudo instruction which ultimately calls m5Syscall already uses sysret, and the implementation of sysret clears both the RF and VM bits itself. There's no reason to do that again explicitly here.
