[PULL 10/15] block: Remove unnecessary NULL check in bdrv_pad_request() |

From: Kevin Wolf <kwolf@redhat.com>
Coverity complains that the check introduced in commit 3f934817 suggests
that qiov could be NULL and we dereference it before reaching the check.
In fact, all of the callers pass a non-NULL pointer, so just remove the
misleading check.
Resolves: Coverity CID 1542668
