[FIX] product,stock: allow label printing w/o doc layout

The default behavior of report_action() is to check if the currently
selected company has their document layout configured. The product
labels do NOT depend on this layout at all though, so let's make it so
the configuration never pops up when product/lot labels are being
printed.
