efa06a2bab bdev: remove free_request bdev backend function
This callback was only used for freeing buffers, but the buffers are now
managed by the bdev core, so none of the free_request callbacks actually
do anything.

9272088d93 bdev: add API to query supported I/O types
Some block devices do not support the unmap operation, and we may add

types a specific block device supports.
