[PATCH] tests/migration: Print some debug on bad status

[Dr. David Alan Gilbert (git)]

From: "Dr. David Alan Gilbert" <dgilb...@redhat.com>

We're seeing occasional asserts in 'wait_for_migraiton_fail', that
I can't reliably reproduce, and where the cores don't have any useful
state.  Print the 'status' out, so we can see which unexpected state
we're ending up in.
