LU-8367 osp: remove unused fail_locs from sanity/27S,822

LU-8367 osp: remove unused fail_locs from sanity/27S,822

OBD_FAIL_OST_GET_LAST_FID and OBD_FAIL_OSP_GET_LAST_FID
are not used anymore since sanity test_27S has been removed.
This may lead to failures in interoperability testing.
For example, 27S caused osp_precreate_cleanup_orphans to
stuck due to not cleared opd_pre_recovering flag(normally,
it should be set to 0 before calling osp_precreate_reserve).
It was the reason of failure tests 27U, 27R, 39r and 51d
in sanity.sh.

The patch also removes OBD_FAIL_NET_ERROR_RPC and
OBD_FAIL_OSP_PRECREATE_PAUSE that were used in sanity-822
"test precreate failure". This test also has been removed
in 63e17799a3.
