qed: honor BDRV_O_INCOMING for incoming live migration
From original commit with Patchwork-id: 31108 by
Stefan Hajnoczi <stefanha@linux.vnet.ibm.com>
"The QED image format includes a file header bit to mark images dirty.
QED normally checks dirty images on open and fixes inconsistent
metadata. This is undesirable during live migration since the dirty bit
may be set if the source host is modifying the image file. The check
should be postponed until migration completes.
Skip operations that modify the image file if the BDRV_O_INCOMING flag
is set."
