Subject: [PATCH 24/46] kernel: Mark function as static in
 kernel/trace/ftrace.c and remove stub declaration from header file
 include/linux/ftrace.h

Mark function as static in kernel/trace/ftrace.c because it is not used
outside this file.
Also, remove unused stub declaration from header file
include/linux/ftrace.h.

This eliminates the following warning in kernel/trace/ftrace.c:
kernel/trace/ftrace.c:4268:6: warning: no previous prototype for ‘ftrace_release_mod’ [-Wmissing-prototypes]
