RDMA/uverbs: Check for null return of kmalloc_array
commit 7694a7de22c53a312ea98960fcafc6ec62046531 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: 6884c6c4bd09 ("RDMA/verbs: Store the write/write_ex uapi entry points in the uverbs_api")
