LU-14111 tests: only support recovery-small test 146 for 2.15.54+

If you running newer clients with older servers (2.15.3) then
recovery-small test 146 will fail since the old servers lack
the new sysfs file eviction_count.

Fixes: 3c69d46e176 ("LU-14111 obdclass: count eviction per obd_device")
Test-Parameters: trivial testlist=recovery-small env=ONLY=146 mdsversion=2.15.3
