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)
