checkpatch: fix EXPORT_SYMBOL handling following a function

The following fragment defeats the DEVICE_ATTR style handing, check for
and ignore the close brace '}' in this context:

    int foo()
    {
    }
    DEVICE_ATTR(link_power_management_policy, S_IRUGO | S_IWUSR,
                ata_scsi_lpm_show, ata_scsi_lpm_put);
    EXPORT_SYMBOL_GPL(dev_attr_link_power_management_policy);
