Jiasheng Jiang 0ea8bb0811 RDMA/uverbs: Check for null return of kmalloc_array ...

commit 7694a7de22 upstream.

Because of the possible failure of the allocation, data might be NULL
pointer and will cause the dereference of the NULL pointer later.
Therefore, it might be better to check it and return -ENOMEM.

Fixes: 6884c6c4bd ("RDMA/verbs: Store the write/write_ex uapi entry points in the uverbs_api")
