x86/ftrace: Move prepare_ftrace_return prototype to header
On 32-bit builds, the prepare_ftrace_return() function only has a global
definition, but no prototype before it, which causes a warning:
arch/x86/kernel/ftrace.c:625:6: warning: no previous prototype for ‘prepare_ftrace_return’ [-Wmissing-prototypes]
625 | void prepare_ftrace_return(unsigned long ip, unsigned long *parent,
Move the prototype that is already needed for some configurations into
a header file where it can be seen unconditionally.
