Subject: [RHEL7.5 PATCH 09/26] mdadm/grow: correct size and chunk_size casting

With commit 4b74a905a67e

("mdadm/grow: Component size must be larger than chunk size") mdadm returns

incorrect message if size given to grow was greater than 2 147 483 647 K.

Cast chunk_size to "unsigned long long" instead of casting size to "int".
