    selftests/pidfd: Fix ksft print formats
    
    [ Upstream commit 4d7f4e8158b62f63031510cdc24acc520956c091 ]
    
    Compiling pidfd selftest after adding a __printf() attribute to
    ksft_print_msg() and ksft_test_result_pass() exposes -Wformat warnings
    in error_report(), test_pidfd_poll_exec_thread(),
    child_poll_exec_test(), test_pidfd_poll_leader_exit_thread(),
    child_poll_leader_exit_test().
    
    The ksft_test_result_pass() in error_report() expects a string but
    doesn't provide any argument after the format string. All the other
    calls to ksft_print_msg() in the functions mentioned above have format
    strings that don't match with other passed arguments.
    
    Fix format specifiers so they match the passed variables.
    
    Add a missing variable to ksft_test_result_pass() inside
    error_report() so it matches other cases in the switch statement.
