x86: Pull dynamic memory allocation out of do_boot_cpu().
This has two advantages:
(a) We can move the allocations to a context where we can handle
failure.
(b) We can implement matching deallocations on CPU offline.
Only the idle vcpu structure is now not freed on CPU offline. This
probably does not really matter.
