eth/tracers/logger: remove unnecessary comparisons in accessList.equal (#24663)

This change removes extraneous/unnecessary checks for equality
when comparing 2 accessList values A and B. Given that we validate that
their lengths of A and B are equal, if so and if every element in A is
in B, reflexively every element in B is already in A. If that weren't
the case and an element g existed in A but not in B, that would mean
that there is an extra element and hence a mathematical contradiction.

Fixes #24658
