blobmsg: fix wrong payload len passed from blobmsg_check_array

Fix incorrect use of blobmsg_len() on passed blobmsg to
blobmsg_check_array_len() introduced in commit 379cd33d19
("fix wrong payload len passed from blobmsg_check_array") by using correct
blob_len().

By using blobmsg_len() a value too small was passed to blobmsg_check_array()
which could lead to this function returning an error when there is none.
