LU-16197 kfilnd: Convert NID num to host order

LU-16197 kfilnd: Convert NID num to host order

The nid_num field in struct lnet_nid is stored in network byte order.
The nid_num field is used to generate the kfabric service string. The
underlying kfabric providers expect the service string to be in host
byte order not network byte order. This mismatch is preventing
multiple LNet NID indexes from being used.

Fix this by converting nid_num to host byte order.
