eth: explicitly commented the code were bor could get into snap-sync mode

[pratikspatil024]

Description

In the recent upstream, this PR was included. As a result of that we observed that node went into snap sync mode. We do not support snap sync at the moment, so in this PR, I have explicitly commented the code were bor could get into snap-sync mode.

Please note that that geth PR is important one when running a PBSS node, so in the future, we will have to find a workaround for the scenarios where the associated head state is missing in PBSS.
