RDMA/core: Fix "KASAN: slab-use-after-free Read in ib_register_device" problem

This problem is similar to the problem that the commit 1d6a9e7449e2 ("RDMA/core: Fix use-after-free when rename device name") fixes.

The root cause is: the function ib_device_rename() renames the name with lock. But in the function kobject_uevent(), this name is accessed without lock protection at the same time.

The solution is to add the lock protection when this name is accessed in the function kobject_uevent().
