linux-user: un-parent OBJECT(cpu) when closing thread

This reinstates commit 52f0c1607671293afcdb2acc2f83e9bccbfa74bb:

While forcing the CPU to unrealize by hand does trigger the clean-up
code we never fully free resources because refcount never reaches
zero. This is because QOM automatically added objects without an
explicit parent to /unattached/, incrementing the refcount.

Instead of manually triggering unrealization just unparent the object
and let the device machinery deal with that for us.

The original patch tickled a problem in target/arm, and was reverted.
But that problem is fixed as of commit 3b07a936d3bf.
