net: add sock_set_reuseaddr
Add a helper to directly set the SO_REUSEADDR sockopt from kernel space without going through a fake uaccess. For this the iscsi target now has to formally depend on inet to avoid a mostly theoretical compile failure. For actual operation it already did depend on having ipv4 or ipv6 support.
