vp_vdpa: Fix return value check vp_vdpa_request_irq
In the vp_vdpa_set_status function, when setting the device status to
VIRTIO_CONFIG_S_DRIVER_OK, the vp_vdpa_request_irq function may fail.
In such cases, the device status should not be set to DRIVER_OK. Add
exception printing to remind the user.
