From c2fc622b771f679e8f55060ac60cfe02b9a80995 Mon Sep 17 00:00:00 2001

Subject: [PATCH] blobmsg: fix length in blobmsg_check_array
blobmsg_check_array_len expects the length of the full attribute buffer,
not just the data length.
Due to other missing length checks (fixed in the next commit), this did
not show up as a test failure
