save_stack_trace() already exists, so change the one in
CONFIG_STACKDEPOT to be save_stack_depot_trace().
Fixes this build error:
../mm/slub.c:607:29: error: conflicting types for ‘save_stack_trace’
static depot_stack_handle_t save_stack_trace(gfp_t flags)
^~~~~~~~~~~~~~~~

extern void save_stack_trace(struct stack_trace *trace);
