kvmclock: Don't crash QEMU if KVM is disabled
Most machines don't allow sysbus devices like "kvmclock" to be
created from the command-line, but some of them do (the ones with
has_dynamic_sysbus=true). In those cases, it's possible to
manually create a kvmclock device without KVM being enabled,
making QEMU crash:
$ qemu-system-x86_64 -machine q35,accel=tcg -device kvmclock
Segmentation fault (core dumped)
This changes kvmclock's realize method to return an error if KVM
is disabled, to ensure it won't crash QEMU.
