hw/riscv: virt: Exit if the user provided -bios in combination with KVM

Browse Source 
The -bios option is silently ignored if used in combination with -enable-kvm.
The reason is that the machine starts in S-Mode, and the bios typically runs in
M-Mode.

Better exit in that case to not confuse the user.
