Subject: rdma-ndd: disable systemd ProtectHostName feature

[ Upstream commit 57637df8dd6b92b4bcd3e04cea476012901526d0 ]

ProtectHostName prevents dynamic name changes to be noticed by the service.
This means that on a system with no static hostname, rdma-ndd is started with
a hostname 'localhost' and is not aware of new hostname retreived
through a DHCP lease.

Fixes: 384b75b5f624 ("rdma-ndd: systemd hardening")
