svcrdma: Address an integer overflow

Dan Carpenter reports:
> Commit 78147ca8b4a9 ("svcrdma: Add a "parsed chunk list" data
> structure") from Jun 22, 2020 (linux-next), leads to the following
> Smatch static checker warning:

> net/sunrpc/xprtrdma/svc_rdma_recvfrom.c:498 xdr_check_write_chunk()
> warn: potential user controlled sizeof overflow 'segcount * 4 * 4'
