sched/task_stack: Add missing const qualifier to end_of_stack()
Add missing const qualifier to the non-CONFIG_THREAD_INFO_IN_TASK
version of end_of_stack() to match the CONFIG_THREAD_INFO_IN_TASK
version. Fixes a warning with CONFIG_KSTACK_ERASE=y on archs that don't
select THREAD_INFO_IN_TASK (such as LoongArch):
error: passing 'const struct task_struct *' to parameter of type 'struct task_struct *' discards qualifiers
The stackleak_task_low_bound() function correctly uses a const task
parameter, but the legacy end_of_stack() prototype didn't like that.
Build tested on loongarch (with CONFIG_KSTACK_ERASE=y) and m68k
(with CONFIG_DEBUG_STACK_USAGE=y).
Fixes: a45728fd4120 ("LoongArch: Enable HAVE_ARCH_STACKLEAK")
