x86/xen: Allow to retry if cpu_initialize_context() failed.
If memory allocation in cpu_initialize_context() fails then it will
bring up the VCPU and leave with the corresponding CPU bit set in
xen_cpu_initialized_map.
The following (presumably successful) CPU bring up will BUG in
xen_pv_cpu_up() because nothing for that VCPU would be initialized.
Clear the CPU bits, that were set in cpu_initialize_context() in case
the memory allocation fails.
