LU-10391 lnet: change LNetAddPeer() to take struct lnet_nid

LU-10391 lnet: change LNetAddPeer() to take struct lnet_nid

Rather than an array of lnet_nid_t, LNetAddPeer now takes an array of
struct lnet_nid.

The array passed is *always* from struct uuid_nid_data, so that data
structure is changed to store struct lnet_nid.
