NLM: Remove address eye-catcher buffers from nlm_host
The h_name field in struct nlm_host is a just copy of
h_nsmhandle->sm_name. Likewise, the contents of the h_addrbuf field
should be identical to the sm_addrbuf field.
The h_srcaddrbuf field is used only in one place for debugging. We can
live without this until we get %pI formatting for printk().
Currently these buffers are 48 bytes, but we need to support scope IDs
in IPv6 presentation addresses, which means making the buffers even
larger. Instead, let's find ways to eliminate them to save space.
