Whether a timeout is linked into the timeout queue can be determined from the corresponding sys_dnode_t linked state. This removes the need to use a special flag value in dticks to determine that the timeout is inactive. Update _abort_timeout to return an error code, rather than the flag value, when the timeout to be aborted was not active. Remove the _INACTIVE flag value, and replace its external uses with an internal API function that checks whether a timeout is inactive. Signed-off-by: Peter A. Bigot <pab@pabigot.com>
