* Add extent to NBDExtentArray. If extent can't be added (no available space),
* return -1.
* For safety, when returning -1 for the first time, .can_add is set to false,
* further call to nbd_extent_array_add() will crash.
* (to avoid the situation, when after failing to add an extent (returned -1),
* user miss this failure and add another extent, which is successfully added
* (array is full, but new extent may be squashed into the last one), then we
* have invalid array with skipped extent)
* and further calls to nbd_extent_array_add() will crash.
* (this avoids the situation where a caller ignores failure to add one extent,
* where adding another extent that would squash into the last array entry
* would result in an incorrect range reported to the client)
