regmap: cache: bail in regmap_async_complete() for bus-less maps
Commit f8bd822cb ("regmap: cache: Factor out block sync") made
regcache_rbtree_sync() call regmap_async_complete(), which in turn does
not check for map->bus before dereferencing it.
This causes a NULL pointer dereference on bus-less maps.
