LU-5604 tgt: return missed fail ids

LU-5604 tgt: return missed fail ids

OBD_FAIL_LDLM_REPLY is missing from tgt_enqueue, and it's actually
not suitable for tgt_enqueue anymore because tgt_enqueue() is a
common handler now.

This patch includes a few changes:
- tgt_enqueue sets tgt_session_info::tsi_reply_fail_id to
  OBD_FAIL_MGS/MDS/OST_LDLM_REPLY_NET based on type of target.

- rewrite test_52 of replay-single, the only reason that test_52
  can pass is because there is a typo:

  $CHECKSTAT -t file $DIR/$tfile-* which should be $DIR/$tfile

- add definitions for OBD_FAIL_LDLM_SRV_CP/BL/GL_AST and resolve
  OBD_FAIL conflictions

- OBD_FAIL_UPDATE_OBJ_NET_REP was renamed to
  OBD_FAIL_OUT_UPDATE_NET_REP but referenced with old name in tests.

- OBD_FAIL_MDS_FAIL_LOV_LOG_ADD check is obsoleted as well as tests.
  Meanwhile the OSP code was updated to fix panic in case of error.

- OBD_FAIL_TGT_LAST_REPLAY is removed along with test. It was never
  used and it seems it was even introduced by mistake.
