STATS shows a denied announcement in v4 for some requests when it shouldn't

[AndrioCelos]

Description

Certain STATS requests provided by modules have return MOD_RES_DENY in the code to stop the core STATS code from also processing the request, but this causes the announcement to show that the request was denied by the module, even though it wasn't.

The following STATS requests have this issue:

• core_oper: oOP
• m_cban: C
• m_geoclass: G
• m_hideoper: P
• m_rline: R
• m_services: S
• m_shun: H
• m_spanningtree: cnU

Steps to reproduce the issue:

1. Log in to an oper account with servers/auspex permission.
2. Make any STATS request listed above.

The output of the command was as follows:
