[PATCH] x86/xen: only unlock when USE_SPLIT_PTE_PTLOCKS is true

When USE_SPLIT_PTE_PTLOCKS is false, xen_pte_lock() actually do nothing but returns NULL. So xen_pte_unlock() should not actually unlock. Otherwise a NULL pointer dereference will be triggered. Fixes: 74260714c56d ("xen: lock pte pages while pinning/unpinning") Signed-off-by: Jason Yan
