tracing, tty: fix warnings caused by branch tracing and tty_kref_get()

Stephen Rothwell reported tht this warning started triggering in
linux-next:

  In file included from init/main.c:27:
  include/linux/tty.h: In function ‘tty_kref_get’:
  include/linux/tty.h:330: warning: ‘______f’ is static but declared in inline function ‘tty_kref_get’ which is not static

Which gcc emits for 'extern inline' functions that nevertheless define
static variables. Change it to 'static inline', which is the norm
in the kernel anyway.
