s390/uv: Fix loop condition in uv_find_secrets

Browse source

Systems with more than 85 UV secrets got -ENOENT for any secret past the
first page.

Fix this by setting the start index at the beginning of the loop in
uv_find_secret() and not at the end. First test if there are more
secrets left by comparing start_idx with list->next_secret_idx, and then
set the start index to the next secret index.
