Subject: [PATCH] dgnc: move more repeating code under 'failed' label

Currently the label is only used to return a error code to the caller but more
repeating code is before each "goto failed;" thus we can move that code to the
label. Also, remove some empty unneeded lines together with this patch in those
if's and at the end of dgnc_found_board().
