Fixes KeyError when processing processors/storage during agent polling.
The sync_processors and sync_storage functions expect device.id to be
the snmp_device id, not the main device id.
Changed from:
%{device_id: device.id}
To:
%{id: device.snmp_device.id}
This matches the expected structure for these sync functions which
query where snmp_device_id == device.id.
