qdev: Use returned bool to check for failure, Coccinelle part

The previous commit enables conversion of

    qdev_prop_set_drive_err(..., &err);
    if (err) {
    ...
    }

to

    if (!qdev_prop_set_drive_err(..., errp)) {
    ...
    }

Coccinelle script:

    @@
    identifier fun = qdev_prop_set_drive_err;
    expression list args;
    typedef Error;
    Error *err;
    @@
    -    fun(args, &err);
    -    if (err)
    +    if (!fun(args, &err))
         {
             ...
         }

One line break tidied up manually.
