[LU-7116] sanity test_17m: e2fsck should not report error upon short/long symlink MDT: rc=4

Description

This issue was created by maloo for Saurabh Tandan <[e-mail]>

This issue relates to the following test suite run: https://testing.hpdd.intel.com/test_sets/13000e1e-53cc-11e5-8f2c-5254006e85c2.

The sub-test test_17m failed with the following error:

e2fsck should not report error upon  short/long symlink MDT: rc=4

The sanity test_17m failed. May be because I ran the tests in different order (not the default order). My testlist consists of tests in following order:

testlist=conf-sanity,ost-pools,recovery-small,replay-dual,replay-ost-single,
replay-single,replay-vbr,sanity,sanity-benchmark,sanity-gss,sanity-krb5,
sanity-quota,sanityn

Not sure if it is dup of LU-3129

There is the patch http://review.whamcloud.com/8982 to run e2fsck after every test, which would help narrow down the source of this corruption.
