Suppress Cppcheck "unused label" warnings

The commit 1d68fae introduced an anonymous bit field, which triggers a
false positive in Cppcheck 2.13.0 (provided by Ubuntu 24.04):
  "Label 'int' is not used. [unusedLabel]".

Although newer versions of Cppcheck resolve this issue, version 2.13 is
still preferable for minimal development environment changes. Instead of
switching versions, this commit drops the anonymous bit field to prevent
the Cppcheck warning.
