qemu: Pass vm to qemuMigrationCookieParse if it exists

Browse Source 
The vm object is used inside qemuMigrationCookieParse based on the flags
passed to qemuMigrationCookieParse and the content of the cookie. The
callers should not just blindly guess and pass NULL if they
(incorrectly) think the vm object is not needed. We should always pass
the vm object unless it does not exist yet.

This fixes a bug when statistics of a completed migration reported
"Unknown" operation instead of "Incoming migration" on the destination
host.
