The VirtIOBlock::rq field has had the type void * since its introduction
in commit 869a5c6df19a ("Stop VM on error in virtio-blk. (Gleb
Natapov)").

Perhaps this was done to avoid the forward declaration of
VirtIOBlockReq.

Hanna Czenczek <hreitz@redhat.com> pointed out the missing type. Specify
the actual type because there is no need to use void * here.
