…k error
- There's a clear asymmetry between the scan (push) side and the pull (fetch) side:
. Scan side (rebuild_objects_send_ult): Already retries ALL daos_crt_network_error()
properly handles transient network errors when pushing OID lists to pullers.
. Pull side (mrone_obj_fetch_internal): Does NOT retry network errors when fetching
data from source
. This patch makes them consistent and always retry for network error for both cases
- rebuild IV refresh can arrive out of order, make sure it doesn't revert global done flag
