Fix a few asserts and IO calls in nscd.
The nscd/*cache.c files contain assert()s, writeall() and sendfileall() calls that invalidly use together &dataset->resp and total where either dataset or dataset->head.recsize should be used instead one of the components. In the writeall() and sendfileall() cases, it is unlikely to matter in practice, but the assertions can fail sometimes without a proper reason.
