signal: update outdated comment for removed freezable_schedule() 



The function freezable_schedule() was removed in commit
f5d39b02 ("freezer,sched: Rewrite core freezer logic"), which
rewrote the freezer to use a dedicated TASK_FROZEN state instead.

do_signal_stop() and ptrace_stop() no longer call
freezable_schedule(); they now set TASK_STOPPED/TASK_TRACED and the
freezer handles those states directly via TASK_FROZEN.  Update the
comment to reflect the current mechanism.
