Subject: hw/9pfs: Initialize rest of qid field to zero.
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=25427ec1437b63e335a30293b58d47b601373223;p=qemu.git

hw/9pfs: Initialize rest of qid field to zero.

Since qid is allocated out of stack we need to intialize
the field to zero. Otherwise we will send wrong qid value
to client.
