x86: suppress trivial sparse signedness warnings
Could just as easily change the three casts to cast to the correct
type...this patch changes the type of ftrace_nop instead.
Supresses sparse warnings:
arch/x86/kernel/ftrace.c:157:14: warning: incorrect type in assignment (different signedness)
arch/x86/kernel/ftrace.c:157:14: expected long *static [toplevel] ftrace_nop
arch/x86/kernel/ftrace.c:157:14: got unsigned long *<noident>
