cmd/evm/t8ntool: add error handling for Commit and state reopening

Browse source 
Previously, both statedb.Commit() and the subsequent state.New() were
ignoring returned errors. This could lead to silent failures where:
1. The commit operation fails but execution continues
2. State reopening fails after a successful commit

Both scenarios can cause difficult-to-debug issues, especially in testing
scenarios where state consistency is critical.

This change adds proper error checking for both operations, ensuring that
any failures are caught immediately with descriptive error messages.

This issue was encountered and fixed in https://github.com/gballet/go-ethereum/pull/552
where the error handling proved essential for debugging.
