ftrace: fix hardirq header for non ftrace archs

Browse source 
Impact: build fix for non-ftrace architectures

Not all archs implement ftrace, and therefore do not have an asm/ftrace.h.
This patch corrects the problem.

The ftrace_nmi_enter/exit now must be defined for all archs that implement
dynamic ftrace. Currently, only x86 does.
