bgpd: Remove unnecessary check for pi and setting type and sub-type

There is code that sets the pi based upon matching it against
the same peer.  In this code the type and sub-type are also
compared to the passed in type and sub-type.  Let's just use
type and sub-type as that if we have a pi we know type and sub-type
are already correct.  This should also make the first iteration
work correctly when the pi has not been created yet when we call
the martian_update function.bgpd: Remove unnecessary check for pi and setting type and sub-type
