File 0014-linux-user-Ignore-broken-loop-ioctl.patch of Package qemu-testsuite.3505

Subject: [PATCH] linux-user: Ignore broken loop ioctl

During invocations of losetup, we run into an ioctl that doesn't
exist. However, because of that we output an error, which then
screws up the kiwi logic around that call.

So let's silently ignore that bogus ioctl.
