[Qemu-devel] [PATCH v2 9/9] quorum: Clean up quorum_aio_get()

[Kevin Wolf <kwolf@redhat.com>]

Make sure that all fields of the new QuorumAIOCB are zeroed when the
function returns even without explicitly setting them. This will protect
us when new fields are added, removes some explicit zero assignment and
makes the code a little nicer to read.
