[LU-2271] recovery-small test 10 does not properly reconnect

Duplicate — Tue, 20 Nov 2012 14:24:09 +0000

It appears that recovery-small test 10 could cause eviction of this client from not only MDS, but also all OSTs.
As the result subsequent test will also fail when it tries to touch one of the not connected OSTs.
(often manifested in test 11 failing ,but if you skip test 11, test 12 will fail, or test 13 if you skip tests 11 and 12).
