x86/stackprotector/64: Only export __ref_stack_chk_guard on CONFIG_SMP
[ Upstream commit 91d5451d97ce35cbd510277fa3b7abf9caa4e34d ]
The __ref_stack_chk_guard symbol doesn't exist on UP:
<stdin>:4:15: error: ‘__ref_stack_chk_guard’ undeclared here (not in a function)
Fix the #ifdef around the entry.S export.
