[PATCH] qemu: don't use initialized ret in qemuRemoveSharedDevice

[Guido Günther <agx@xxxxxxxxxxx>]

This fixes

  CC     qemu/libvirt_driver_qemu_impl_la-qemu_conf.lo
  qemu/qemu_conf.c: In function 'qemuRemoveSharedDevice':
  qemu/qemu_conf.c:1384:9: error: 'ret' may be used uninitialized in this function [-Werror=maybe-uninitialized]
---
This is only catched by Debian Wheezy's gcc 4.7.2, Jessies gcc 4.9.2 doesn't
trap on it.
