Easiest thing: reboot your machine.
If you can't do that, unload the nvidia module and then reload it:
rmmod nvidia
modprobe nvidia
The underlying issue is that you have upgraded the nvidia kernel module
rpm, but the loaded version was still the old one so the nvidia driver
(in nvidia-x11-drv) was detecting the wrong version. Rebooting will
solve that problem, especially if there has been a new kernel
installed.
BTW, the clue is really in the error message from the kernel, it
basically tells you what needs to happen without explicitly telling you
the steps to do it.
