Subject: qcow2: Don't try to check tables that couldn't be loaded
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=f74550fd53598ac6529dbcfc3c06e98d2d7fbe51;p=qemu.git

qcow2: Don't try to check tables that couldn't be loaded

Trying to check them leads to a second error message which is more confusing
than helpful:

    Can't get refcount for cluster 0: Invalid argument
    ERROR cluster 0 refcount=-22 reference=1
