From: Andreas Dilger <adilger@whamcloud.com>

Remove the obsolete OBD_LOG_CANCEL (since Lustre 1.5) and
OBD_QC_CALLBACK (since Lustre 2.4) RPC opcodes.

Assign  OBD_IDX_READ an explicit opcode (as should be done with all
enums in lustre_idl.h) so that the value does not change if some
prior field is removed.

Also remove the OBD_FAIL checks that were used to test them.
The setting in conf_sanity.sh test_58 was unused for many years.
