[PATCH 2/2] tests/migration/postcopy: trim migration bandwidth

["Dr. David Alan Gilbert (git)" <dgilbert@redhat.com>]

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

On slow hosts with tcg we were sometimes finding that the migration
would complete during precopy and never get into the postcopy test.
Trim back the bandwidth a bit to make that much less likely.
