net: dns_resolver: convert time_t to time64_t

Changes the definition of the pointer _expiry from time_t to time64_t. This is to handle the Y2038 problem where time_t will overflow in the year 2038. The change is safe because the kernel subsystems that call dns_query pass NULL. Signed-off-by: Arnd Bergmann <[email protected]> Signed-off-by: Aya Mahfouz <[email protected]> Signed-off-by: David S.
