Warnings even when using the 'Recommended querier timeout'

[LouisAtGH]

I noticed the following warnings in the system log:
Dec 18 13:33:19 pfSense pimd[24]: Recommended querier timeout = Robustness x query-interval + response-time / 2 = 3 x 12 + 10 / 2 = 41

Which is in two regards strange:

• the default used to be 42 and
• given this warning I changed it to 41

And the warning is still there and repeating with some frequency

After noticing this I checked the actual settings with pimctl show status, which confirmed that the query interval is the advised 41

Yeah this should be changed to follow the RFC values for query and timeout (180 and 300 iirc).

Thank you for the reminder 👍
