Blockdevs already indicate support for unmap via
spdk_bdev_io_type_supported(bdev, SPDK_BDEV_IO_TYPE_UNMAP).

The user can get there via the bdev, so this didn't
have a purpose.

Some calls were passing bdev->ctxt, some calls just
bdev. In most of our implementations those are the
same pointer, but they aren't necessarily.

This is consistent with the rest of the RPC calls that report a number
of blocks, and it matches the field in the split_disk structure.

The driver_specific object should contain a single object with the
blockdev driver's name so that the user can determine how to interpret
it. This matches the NVMe blockdev driver.

Since the io_channel will be passed to the underlying bdev's
read/write/... functions later, we need to also acquire an io_channel
for the underlying bdev, not for the virtual bdev.

This virtual block device takes an underlying block device and splits it
into several smaller equal-sized block devices.
