core/vm: remove panic when address is not present (#30414)

Remove redundant address presence check in `makeGasSStoreFunc`.

This PR simplifies the `makeGasSStoreFunc` function by removing the
redundant check for address presence in the access list. The updated
code now only checks for slot presence, streamlining the logic and
eliminating unnecessary panic conditions.

This change removes the unnecessary address presence check, simplifying
the code and improving maintainability without affecting functionality.
The previous panic condition was intended as a canary during the testing
phases (i.e. _YOLOv2_) and is no longer needed.
