Fix pflash migration
Pflash migration (e.g. q35 + EFI variable storage) fails
with the assert:
bdrv_co_do_pwritev: Assertion `!(bs->open_flags & 0x0800)' failed.
This avoids the problem by delaying the pflash update until after
the device loads complete.
Tested by:
Migrating Q35/EFI vm.
Changing efi variable content (with efiboot in the guest)
md5sum'ing the variable file before migration and after.
This is a fix that Paolo posted in the message
