rgw: fix bucket sync thread waiting inordinate amount of time

A signed value was read in as an unsigned value, so -1 was interpreted
as a very large value. This made the thread wait period in the bucket
sync thread inordinately long, preventing bucket sync and dynamic
resharding (unless values appropriate for debugging were set).
