ftrace: use init_struct_pid as swapper pid
Impact: clean up Using (struct pid *)-1 as the pointer for ftrace_swapper_pid is a little confusing for others. This patch uses the address of the actual init pid structure instead. This change is only for clarity. It does not affect the code itself. Hopefully soon the swapper tasks will all have their own pid structure and then we can clean up the code a bit more.
