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.

Aborted (core dumped) If we try postcopy with a similar scenario, we also get the writev error message but QEMU leaves the guest paused because entered_postcopy is true. We could possibly do the same with precopy and leave the guest paused. But since the historical default for migration errors is to restart the source, this patch adds a call to bdrv_invalidate_cache_all() instead.
