net: fix sparse warning in sk_dst_set()

sk_dst_cache has __rcu annotation, so we need a cast to avoid
following sparse error :

include/net/sock.h:1774:19: warning: incorrect type in initializer (different address spaces)
include/net/sock.h:1774:19:    expected struct dst_entry [noderef] <asn:4>*__ret
include/net/sock.h:1774:19:    got struct dst_entry *dst
