[Qemu-devel] [PULL 29/31] qemu-io: Fix recent UI updates

[Kevin Wolf <kwolf@redhat.com>]

From: Eric Blake <eblake@redhat.com>

Commit 770e0e0e [*] tried to add 'writev -f', but didn't tweak
the getopt() call to actually let it work.  Likewise, commit
c2e001c missed implementing 'aio_write -u -z'.  The latter commit
also introduced a leak of ctx.

[*] does it sound "ech0e" in here? :)
