migration/migration.c: Fix hang in ram_save_host_page

migration_rate_limit will erroneously ratelimit a shutdown socket,
which causes the migration thread to hang in ram_save_host_page
if the socket is shutdown.

Fix this by explicitly testing if the socket has errors or was
shutdown in migration_rate_limit.
