[PATCH v2 2/2] vfio/ccw: Return false when IRQ notifier setup fails

[zhaoguohan]

From: GuoHan Zhao <zhaoguo...@kylinos.cn>

vfio_ccw_register_irq_notifier() cleans up the fd handler and EventNotifier
when vfio_device_irq_set_signaling() fails, but still returns true to its
caller.

Return false after cleanup so the caller can handle the failed
registration path instead of treating it as a successful notifier setup.

Fixes: 8aaeff97acee ("vfio/ccw: Make vfio_ccw_register_irq_notifier() return a 
bool")
