LU-12610 obd: delete OBD_ -> CFS_ redefinitions

With all consumers of the OBD macros fixed, finally
remove OBD macros that are simply redefinitions of CFS
macros.

Remove:
OBD_FAIL_PRECHECK(id)
OBD_FAIL_CHECK(id)
OBD_FAIL_CHECK_VALUE(id, value)
OBD_FAIL_CHECK_ORSET(id, value)
OBD_FAIL_CHECK_RESET(id, value)
OBD_FAIL_RETURN(id, ret)
OBD_FAIL_TIMEOUT(id, secs)
OBD_FAIL_TIMEOUT_MS(id, ms)
OBD_FAIL_TIMEOUT_ORSET(id, value, secs)
OBD_RACE(id)
OBD_FAIL_ONCE
OBD_FAILED

Avoid losing the unlikely optimization with OBD_FAIL_PRECHECK by
adding unlikely to CFS_FAIL_PRECHECK. For libcfs_private.h not
all callers of CFS_FAIL_PRECHECK had unlikely so this is fixed
as well.
