network: Fix max recommended bitrate check

[prgmitchell]

Description

Fix false negatives by only checking the bitrate that is immediately after the service recommendations.

Motivation and Context

Noticed some issues with logs posted in the OBS discord server. After fixing/testing I noticed that #184 was submitted. When running my test logs against that PR I found some issues, for example https://obsproject.com/logs/3zpBZBLcluZG6A3Q throws an error. Rather than trying to leave feedback on that and troubleshoot I just decided to submit this PR since it was already complete.

How Has This Been Tested?
