[Qemu-stable] [PATCH 18/51] migration: Fix rate limit

[Michael Roth]

From: Matthew Garrett <address@hidden>

The migration thread appears to want to allow writeout to occur at full
speed rather than being rate limited during completion of state saving,
but sets the limit to INT_MAX when xfer_limit is INT64_MAX. This causes
problems if there's more than 2GB of state left to save at this point. It
probably ought to just be INT64_MAX instead.
