Subject: driver core: bus: Goto appropriate labels on failure in bus_add_device

From: Junjie Mao <junjie_mao@yeah.net>

commit 1c34203a1496d1849ba978021b878b3447d433c8 upstream.

It is not necessary to call device_remove_groups() when device_add_groups()
fails.

The group added by device_add_groups() should be removed if sysfs_create_link()
fails.

Fixes: fa6fdb33b486 ("driver core: bus_type: add dev_groups")
