This is a follow-up of commit:

  cfd8983f ("x86, locking/spinlocks: Remove ticket (spin)lock implementation")

The static_key structure 'paravirt_ticketlocks_enabled' is now removed as it is
no longer used.

As a result, the init functions kvm_spinlock_init_jump() and
xen_init_spinlocks_jump() are also removed.

A simple build and boot test was done to verify it.
