nwserv: escape remaining protocol names in debug logs

Use the bounded printable formatter for two remaining debug paths that can
log protocol-derived byte fields directly.

The SAP route suppression log can print SAP-derived server names, including
non-printable bytes advertised by newer NetWare service types.  The namespace
search diagnostic can also contain DOS wildcard bytes such as 0xff padding.

Format both fields through visable_data() so diagnostics stay readable and do
not emit raw control or high-bit bytes.

This is logging-only and does not change SAP, routing, or namespace behavior.
