Zhengchao Shao cf2010aa1c netdevsim: fix memory leak in nsim_bus_dev_new() 
If device_register() failed in nsim_bus_dev_new(), the value of reference
in nsim_bus_dev->dev is 1. obj->name in nsim_bus_dev->dev will not be
released.

unreferenced object 0xffff88810352c480 (size 16):
  comm "echo", pid 5691, jiffies 4294945921 (age 133.270s)
