[PATCH V2 1/2] [BUGFIX] virtio/console: Quit from splice_write if pipe->nrbufs is 0
...ufs.
(4) The virtio-console driver tries to touch scatterlist structure sgl in
sg_init_table(), but the region is out of bound.
To avoid the case, a kernel should check whether pipe->nrbufs is empty or not
when splice_write is executed in the virtio-console driver.
