Subject: [PATCH 1/2] rasdaemon/diskerror: fix incomplete diskerror log

Currently, rasdaemon output incomplete diskerror log(only contains timestamp):
<idle>-0     [000]     0.017915: block_rq_complete:    2022-12-16 04:17:32 +0800

Fix incomplete diskerror log just like block_rq_complete tracepoint output format:
<idle>-0       [042] d.h. 177962.715669: block_rq_complete: 21,0 N () 18446744073709551615 + 0 [-121]
