Before previous patch, iotest 169 was actually broken for the case
7711c0
test_persistent__not_migbitmap__offline_shared, while formally
7711c0
passing.
7711c0
7711c0
After migration log of vm_b had message:
7711c0
7711c0
    qemu-system-x86_64: Could not reopen qcow2 layer: Bitmap already
7711c0
    exists: bitmap0
7711c0
7711c0
which means that invalidation failed and bs->drv = NULL.
7711c0
7711c0
It was because we've loaded bitmap twice: on open and on invalidation.
7711c0
7711c0
Add code to 169, to catch such fails.
