LU-17428 tests: restore recovery-small/10a lru_max_age

LU-17428 tests: restore recovery-small/10a lru_max_age

Restore the longer lru_max_age in recovery-small test_10a since
this otherwise prevents the client from being evicted.

Skip the console message check for stuck MDS threads on subsequent
iterations of test_10a when the test is run in a loop, since message
ratelimiting may prevent the console message from being printed.

Test-Parameters: trivial testlist=recovery-small env=ONLY=10a,ONLY_REPEAT=10
Fixes: 357cae970c ("LU-17428 ldlm: reduce default lru_max_age")
