Subject: osd/OSD.cc: remove osd_lock for bench
X-Git-Tag: v16.1.0~1639^2

osd/OSD.cc: remove osd_lock for bench

8987f94416f453829eae6dda08837ef5a42531c6 introduced the osd_lock for the
bench command. Taking the osd_lock in bench can lead to deadlocks, causing the
command to hang as seen in https://tracker.ceph.com/issues/43888.
