[Qemu-devel] [PULL 36/62] block: use the standard 'ret' instead of 'result'

[Kevin Wolf <kwolf@redhat.com>]

From: Jeff Cody <jcody@redhat.com>

Most QEMU code uses 'ret' for function return values. The VDI driver
uses a mix of 'result' and 'ret'.  This cleans that up, switching over
to the standard 'ret' usage.
