Eric Farman c4c41a0a65 block: get max_transfer limit for char (scsi-generic) devices ...

We can get the maximum number of bytes for a single I/O transfer
from the BLKSECTGET ioctl, but we only perform this for block
devices.  scsi-generic devices are represented as character devices,
and so do not issue this today.  Update this, so that virtio-scsi
devices using the scsi-generic interface can return the same data.
