[PATCH] i386: Don't delete cpu_devs data to identify different x86 types in late_initcall

In arch/i386/cpu/common.c there is:
cpu_devs[X86_VENDOR_INTEL]
cpu_devs[X86_VENDOR_CYRIX]
cpu_devs[X86_VENDOR_AMD]
...
They are all filled with data early.
The data (struct) got set to NULL for all, but Intel in different
late_initcall (exit_cpu_vendor) calls.
I don't see what sense this makes at all, maybe something that got
forgotten with the HOTPLUG_CPU extenstions?

Please check/review whether initdata, cpuinitdata is still ok and this
still works with HOTPLUG_CPU and without, it should...
