[PATCH v2 0/2] fix qcow2_can_store_new_dirty_bitmap

[Vladimir Sementsov-Ogievskiy]

Hi all!

Here is a fix for persistent bitmaps managing: we must check existent
but not yet stored bitmaps for qcow2-related constraints, like maximum
number of bitmaps in qcow2 image.

v2:

01: change assertion to error-return at function start
    Be free to add
    Reported-by: aihua liang <address@hidden>
    Fixes: https://bugzilla.redhat.com/show_bug.cgi?id=1712636
    if it's appropriate
02: new test
    Ohh, it takes about 4 minutes. Be free to drop it, as I doubt that
    it worth to have. The case is simple, we may live without a
    test.
