Laszlo spotted and studied this wasteful "if". He pointed out:
The original virtio_blk_free_request needed an "if" as it accesses one
field, since 671ec3f056 ("virtio-blk: Convert VirtIOBlockReq.elem to
pointer", 2014-06-11); later on in f897bf751f ("virtio-blk: embed
VirtQueueElement in VirtIOBlockReq", 2014-07-09) the field became
embedded, so the "if" became unnecessary (at which point we were using
g_slice_free(), but it is the same.
Now drop it.
