[PATCH for-next] RDMA/core: Remove unnecessary statements

[Yajun Deng <yajun.deng@linux.dev>]

The rdma_zalloc_drv_obj() in __ib_alloc_pd() would zero pd, it unnecessary
add NULL to the object in struct pd.

The uverbs_free_pd() already return busy if pd->usecnt is true, there is
no need to add a warning.
