[PATCH iproute2 V2] iplink: Update usage in help message

[Tariq Toukan <tariqt@mellanox.com>]

From: Eli Cohen <eli@mellanox.com>

Add to usage message a description of how to configure Infiniband node
and port GUIDs. Also modify the man page to emphasize the GUIDs are
configured for Infiniband VFs.

Fixes: d91fb3f4c7e4 ("Add support for configuring Infiniband GUIDs")
