bgpd: When receiving a route set the label to invalid

When we are receiving a route the attr->extra->label_index
is being set to 0.  This should be BGP_INVALID_LABEL_INDEX
instead since we cannot rely on 0 to be correct for labels.

I believe that there are probably other spots that need this
type of fix, but I will let testing snuggle-bump them out.
