Fix kVM_GET_ONE_REG interface

Qemu-1.0 included some code to use a new get/set one register interface
to KVM which unfortunately hadn't settled, and in the end the code that
went into the kernel provides a different interface.  This updates qemu
to use the new interface.

Since the 3.3 kernel doesn't provide this interface, in either the new
or the old form, this removes the check that caused qemu to bail out
if the ioctl returns an error.  In fact we don't even print a message,
since it got printed once per vcpu, which gets a bit tedious with more
than a few vcpus.
