Stefano Garzarella 9b06d0d076 block/blkio: add more comments on the fd passing handling 
As Hanna pointed out, it is not clear in the code why qemu_open()
can fail, and why blkio_set_int("fd") is not enough to discover
the `fd` property support.

Let's fix them by adding more details in the code comments.
