This patch fixes some hurd bits from commit afcf3cd8eb that added the
__access_noerrno internal symbol. It basically removes the nonrequired
__hurd_fail_noerrno (since the 'err' argument is ignored) and fixes
a typo for EACCES.
However, as stated on maillist [1] this __access_noerrno may still be
unsafe to run during initialization of tunables on the Hurd. The
access_common calls __hurd_file_name_lookup, which calls
__hurd_file_name_lookup_retry, which can set errno.
