nscd: Use errval, not errno to guide cache update (bug 30662)
The errno variable is potentially clobbered by the preceding send call. It is not related to the to-be-cached information. The parallel code in hstcache.c and servicescache.c already uses errval. Reviewed-by: Siddhesh Poyarekar <siddhesh@sourceware.org>
