block: add 'node-name' field to BLOCK_IMAGE_CORRUPTED

Since this event can occur in nodes that cannot have a device name
associated, include also a field with the node name.

BLOCK_IMAGE_CORRUPTED
---------------------
Emitted when a disk image is being marked corrupt.
Emitted when a disk image is being marked corrupt. The image can be
identified by its device or node name. The 'device' field is always
present for compatibility reasons, but it can be empty ("") if the
image does not have a device name associated.
Data:
- "device": Device name (json-string)
- "msg": Informative message (e.g., reason for the corruption) (json-string)
- "offset": If the corruption resulted from an image access, this is the access
offset into the image (json-int)
- "size": If the corruption resulted from an image access, this is the access
size (json-int)
- "device": Device name (json-string)
- "node-name": Node name (json-string, optional)
- "msg": Informative message (e.g., reason for the corruption)
(json-string)
- "offset": If the corruption resulted from an image access, this
is the access offset into the image (json-int)
- "size": If the corruption resulted from an image access, this
is the access size (json-int)
Example:
{ "event": "BLOCK_IMAGE_CORRUPTED",
"data": { "device": "ide0-hd0",
"data": { "device": "ide0-hd0", "node-name": "node0",
"msg": "Prevented active L1 table overwrite", "offset": 196608,
