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.
SAP service names are fixed-size 48-byte fields and are not guaranteed to be
safe C strings in diagnostics. Some NetWare 6.5 SAP service types advertise
non-printable or high-bit bytes in the name field, which made the debug log
hard to read and could run past the intended protocol field if logged with a
plain %s.
Add bounded formatting for SAP names used in debug output. Stop at NUL within
the fixed field, keep printable ASCII unchanged, and escape other bytes as
\\xNN.
This is logging-only and does not change SAP/RIP protocol behavior.
