Voice "Packets Lost" statistic was reported incorrectly

[Dan-Linden]

Environment

Second Life Release 26.2.0.24476400809
Mac

Description

I saw a very high number of packets lost after teleporting between some vivox and WebRTC regions on Mac.

Reproduction steps

Repro steps:

• (This is a best guess. I was not able to reproduce this bug a second time)
• Log in on a Vivox region (I happened to be on a Mac. I doubt that is a requirement)
• Watch the Voice > Incoming audio > Packets lost stat in the Statistics floater.
• Teleport between some vivox and WebRTC regions

Observed: The reported packets was very high.
