QOM instance_init functions are not supposed to have any side-effects,
as new objects may be created at any moment for querying property
information (see qmp_device_list_properties()).
Calling cpu_exec_init() also affects QEMU's ability to handle errors
during CPU creation, as some actions done by cpu_exec_init() can't be
reverted.
Move cpu_exec_init() call to realize so a simple object_new() won't
trigger it, and so that it is called after some basic validation of CPU
parameters.
