[PATCH] lib/stackdepot: fix obsolete comments

[Miles Chen]

This change replaces "depot_save_stack" with "stack_depot_save"
in code comments because that depot_save_stack() is replaced by
stack_depot_save() in commit c0cfc337264c ("lib/stackdepot: Provide
functions which operate on plain storage arrays") and depot_save_stack()
is removed in commit 56d8f079c51a ("lib/stackdepot: Remove
obsolete functions")
