kasan: use stack_depot_put for tag-based modes
Make tag-based KASAN modes evict stack traces from the stack depot once
they are evicted from the stack ring.
Internally, pass STACK_DEPOT_FLAG_GET to stack_depot_save_flags (via
kasan_save_stack) to increment the refcount when saving a new entry to
stack ring and call stack_depot_put when removing an entry from stack
ring.
