Revert "Per defaul probe max to 2x current BWE if max total allocated bitrate change"

This reverts commit 37458ce40a1741f9d5358d49fe49beed20140502.

Reason for revert: Will be wired up as an experiment instead. 

Original change's description:
> Per defaul probe max to 2x current BWE if max total allocated bitrate change
>
> This aligns to probe limits in ALR for example.
