LU-13340 mgs: change record_add_uuid() to take large nids

LU-13340 mgs: change record_add_uuid() to take large nids

This just changes the function signature and does not really
change any functionality, because it always just converts the
struct lnet_nid back to lnet_nid_t.

Future patches will make more sense of this.
