Subject: slub: STACKDEPOT: rename save_stack_trace()
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)
^~~~~~~~~~~~~~~~

from ../mm/slub.c:13:
../include/linux/stacktrace.h:86:13: note: previous declaration of `save_stack_trace' was here
extern void save_stack_trace(struct stack_trace *trace);
