[PATCH] x86/x2apic: Make set_x2apic_phys_mode __init

[Dou Liyang <douly.fnst@cn.fujitsu.com>]

The early_param() is only called during kernel initialization, So Linux
marks the functions of it with __init macro to save memory.

But it forgot to mark set_x2apic_phys_mode(). So, Make it __init as well.
