locking/spinlocks/x86, paravirt: Remove paravirt_ticketlocks_enabled
This is a follow-up of commit:
cfd8983f03c7b2 ("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.
