[PATCH 3.16.y-ckt 155/180] driver core: bus: Goto appropriate labels on failure in bus_add_device

[Luis Henriques]

3.16.7-ckt11 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Junjie Mao <junjie_mao@xxxxxxxx>

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")
