[PATCH] xen x86: fix early boot crash with gcc-10

The change fixes boot failure on VM where kernel (at least v5.4 and v5.6) is built with gcc-10 and STACKPROTECTOR_STRONG enabled: ``` Kernel panic - not syncing: stack-protector: Kernel stack is corrupted in: cpu_bringup_and_idle+0x93/0xa0 CPU: 1 PID: 0 Comm: swapper/1 Not tainted 5.4.31-1.qubes.
