Yang Yingliang 7f21735ffb rbd: fix possible memory leak in rbd_sysfs_init() 
If device_register() returns error in rbd_sysfs_init(), name of kobject
which is allocated in dev_set_name() called in device_add() is leaked.

As comment of device_add() says, it should call put_device() to drop
the reference count that was set in device_initialize() when it fails,
so the name can be freed in kobject_cleanup().

Fault injection test can trigger this problem:

unreferenced object 0xffff88810173aa78 (size 8):
  comm "modprobe", pid 247, jiffies 4294714278 (age 31.789s)
  hex dump (first 8 bytes):
    72 62 64 00 81 88 ff ff                          rbd.....
  backtrace:
