Fix type error in kvm/GetMigrationStatus
Commit
6a1434d7 (“Make migration RPC non-blocking”) changed from
raising HypervisorErrors to returning MigrationStatus
objects. However, these objects don't have an "info" attribute, so
they can't pass a reason back (which is in itself a bug); but the KVM
hypervisor code attempts to do so, and fails at runtime with:
Failed to get migration status: 'MigrationStatus' object has no attribute 'info'
instead of the intended:
Migration failed, aborting: too many broken 'info migrate' answers
For now (on stable-2.6), let's just remove the "info" reason, and
later we can add it back properly once we have a way to correctly
represent migration status failures in the LU.
This fixes issue 297.
