migration: Call blk_resume_after_migration() for postcopy
Commit d35ff5e6 ('block: Ignore guest dev permissions during incoming migration') added blk_resume_after_migration() to the precopy migration path, but neglected to add it to the duplicated code that is used for postcopy migration. This means that the guest device doesn't request the necessary permissions, which ultimately led to failing assertions. Add the missing blk_resume_after_migration() to the postcopy path.
