x86/paravirt: Set up the virt_spin_lock_key after static keys get initialized

Commit:

  9043442b43b1 ("locking/paravirt: Use new static key for controlling call of virt_spin_lock()")

sets the static virt_spin_lock_key to a value before jump_label_init()
has been called, which will result in a WARN().

Reorder the initialization sequence:

 - Move the native_pv_lock_init() into native_smp_prepare_cpus()
 - set the value in xen_init_lock_cpu()

to avoid calling into the not yet initialized static keys subsystem.
