[PATCH 25/46] kernel: Add prototype declaration to header file include/linux/ftrace.h

Add prototype declaration of function to header file
include/linux/ftrace.h because it is used by more than one file.

This eliminates the following warning in kernel/trace/ftrace.c:
kernel/trace/ftrace.c:4914:5: warning: no previous prototype for ‘ftrace_graph_entry_stub’ [-Wmissing-prototypes]
