Description

- https://pulpito.ceph.com/vshankar-2022-05-02_16:58:59-fs-wip-vshankar-testing1-20220502-201957-testing-default-smithi/6818701/

Depending on the kernel version used in the test, read counts (stats) fetched via debugfs is either a file or are available under a subdirectory. This results in qa failures such as:

022-05-02T17:21:28.642 DEBUG:teuthology.orchestra.run.smithi070:> (cd /home/ubuntu/cephtest/mnt.0 && exec bash -c 'sudo dd if=/sys/kernel/debug/ceph/3bb12bbe-a08f-4e75-a997-1fda2e936e60.client5047/metrics/size')
2022-05-02T17:21:28.720 INFO:teuthology.orchestra.run.smithi070.stderr:dd: failed to open '/sys/kernel/debug/ceph/3bb12bbe-a08f-4e75-a997-1fda2e936e60.client5047/metrics/size': Not a directory

mount::get_op_read_count() should handle this case (fallback to older way of fetching read stats).
