This avoids each test needing to add it to suppress windows popping up.

[Commit 7ceeedd0 ("blockdev-test: add
test case for drive_add duplicate IDs") and commit
43cd2098 ("qdev-monitor-test: add
device_add leak test cases") added qtest tests without specifying
-display none.

As a result, "make check" now tries to use graphics (GTK or SDL).  Since
graphics are not used by the test and inappropriate for headless "make
check" runs, add the missing -display none.

This fixes "make check" in the QEMU buildbot.

This patch moves ret assignment after reporting original error.

We were lucky to pass qemu-iotests 048 (qemu-img compare case) but when
I tried to run with TEST_DIR=/tmp (tmpfs), it fails with a "wrong"
mismatch offset. This fixes two bugs.

In the first if branch, setting ret to 1 before using it makes dead code
in the next line: pnum is never added to mismatch offset even if ret was
0.

In the other if branch, currently the output error is always -4:
  strerror(-4) -> Unknown error -4

Added regression test in case 048.

If backing file doesn't exist, the error message is confusing and
misleading:

    $ qemu /tmp/a.qcow2
    qemu: could not open disk image /tmp/a.qcow2: Could not open file: No
    such file or directory

But...

    $ ls /tmp/a.qcow2
    /tmp/a.qcow2

    $ qemu-img info /tmp/a.qcow2
    image: /tmp/a.qcow2
    file format: qcow2
    virtual size: 8.0G (8589934592 bytes)
    disk size: 196K
    cluster_size: 65536
    backing file: /tmp/b.qcow2

Because...

    $ ls /tmp/b.qcow2
    ls: cannot access /tmp/b.qcow2: No such file or directory

This is not intuitive. It's better to have the missing file's name in
the error message. With this patch:

    $ qemu-io -c 'read 0 512' /tmp/a.qcow2
    qemu-io: can't open device /tmp/a.qcow2: Could not open backing
    file: Could not open '/stor/vm/arch.raw': No such file or directory
    no file open, try 'help open'
