[Qemu-devel] [PULL 35/35] virtio-scsi: fix dataplane

[Paolo Bonzini]

Commit 361dcc7 (virtio-scsi: dataplane: fail setup gracefully, 2014-10-15)
actually broke successful dataplane setup in a not-so-graceful manner:

    qemu-system-x86_64: .../util/rfifolock.c:71: rfifolock_unlock: Assertion 
`r->nesting > 0' failed.

due to a missing return statement.
