scripts: ci: check_compliance: fix potential unbound variable access

When checking for emails/sign-off, if parsing of the commit information
using 'git show' fails, the 'auth_name', 'auth_email' and 'body' variables
are unbound but accessed right afterwards, which would cause an error.

Skip straight to next iteration of the loop when such an error occurs to
ensure access to the unbound variables is never performed.

This error was reported by the VS Code Pylance analyzer.
