LU-3134 utils: Fix compilation errors in packet_lustre.c

There are compilation errors in packet_lustre.c when building
Wireshark plugins. This was introduced in
http://review.whamcloud.com/#change,2877.  That patch was deleting
llog variables no longer needed.  Not all instances got deleted.

LU-3000 tests: several fixes of tests for DNE

1. sanity 27u, set PRECREATE_FAIL for every MDS.

2. sanity 133d, use mkdir, instead of test_mkdir to
avoid checking rename stats on remote MDTs.

3. conf-sanity 32, use do_rpc_nodes for reload module,
in case it needs to reload module on remote nodes, and
also umount mdt2 in 32c.

4. conf-sanity 42, add load_modules to avoid missing
module errors in some cases.

5. skip test_53 and test_225 when there are more than
one MDT.

6. redirect error message to /dev/null, to avoid
too much error message in the log, which might
explore the size of the log.

Test-parameters: mdscount=2 mdtcount=2 testlist=sanity,conf-sanity
