Coverity notices that the checks against mkstemp() failing in create_qcow2_with_mbr() are wrong: mkstemp returns -1 on failure but the check is just "g_assert(fd)". Fix to use "g_assert(fd >= 0)", matching the correct check in create_test_img(). Fixes: Coverity CID 1432274 Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
