Debugging infrastructure for async objs: this lets us easily create fast_lists for various object types so they'll be visible in debugfs. Add new object types to the BCH_ASYNC_OBJS_TYPES() enum, and drop a pretty-printer wrapper in async_objs.c. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
