Commit Message

Remove the redundant masking of "hart_idx", as the same operation is
performed later during address calculation.

This change impacts the "hart_idx" value in the final qemu_log_mask()
call. The original "hart_idx" parameter should be used for logging to
ensure accuracy, rather than the masked value.

Please add a changelog here when sending new versions. In this case,
it could just be

  v2: Improved commit message and added text about qemu_log_mask
      to the commit message

Also CC reviewers of previous versions even if they weren't CC'ed
on the version they reviewed.
