regmap: ram: fix memory leaks in __regmap_init_ram() on error

Two allocations in __regmap_init_ram() are not cleaned up on failure.

If the kzalloc_objs() for data->written fails, data->read is returned
with no way for the caller to free it.

If __regmap_init() fails, neither data->read nor data->written is freed
because its error paths do not call bus->free_context() (which is
regmap_ram_free_context() here). Only regmap_exit() does, and that is
never reached on an init failure.

Free the allocated arrays before returning any error.
