Reverts 341580e8f4e7c83d0382fc7d40281b5ac973e568 in favor of more simple
logic. A longer term solution needs to be implemented for the race
condition where the `gas-oracle` front runs a tx that has already passed
gas validation at the policy layer.

The `gas-oracle` tx can increase the L1 gas portion of the fee,
causing the tx that already passed the policy check to fail during
consensus execution. This should never happen.
