I played around and I found a solution, that maybe helps someone else too:

I installed now a virtual machine with MFSBSD and upgraded it using
freebsd-update.
Upgrade was successfully done, I copied the boot folder to the PC the
upgrade is failing, modified the loader.conf and reboot is fine now.
It seems that freebsd-update damaged each time the boot folder while
doing the upgrade which causes it to fail on rebooting the new kernel.
