executor/common_linux.h: remove assumption that netlink always returns nonpositive error codes
The code in common_linux.h assumes that nlmsgerr can either be 0 or a
negative value in case of an error. However, this is not always the
case. For example, some commands of mac80211_hwsim use nonnegative
values to indicate success (e.g. HWSIM_CMD_NEW_RADIO returns either a
negative error or a nonnegative radio index). Therefore, negation of
error code inside netlink_send_ext is not correct.
This patch changes this behavior. Now netlink_send_ext returns the
exact value it received via netlink.
