media: solo6x10: fix possible memory leak in solo_sysfs_init()

Browse source 
[ Upstream commit 7f5866dd96 ]

If device_register() returns error in solo_sysfs_init(), the
name allocated by dev_set_name() need be freed. As comment of
device_register() says, it should use put_device() to give up
the reference in the error path. So fix this by calling
put_device(), then the name can be freed in kobject_cleanup().
