[PATCH] x86/cyrix: Replace deprecated strcpy() with strscpy()

[PATCH] x86/cyrix: Replace deprecated strcpy() with strscpy()

[Thorsten Blum]

strcpy() is deprecated; use strscpy() instead.

Remove the local variable 'char *buf' and call strscpy() directly with
'c->x86_model_id', allowing the compiler to infer the fixed size of the
destination buffer using sizeof().

Note: I already submitted this in April as part of another patch [1]
which doesn't apply anymore. Submitting this again as a separate patch.
