odp-util: Fix fuzz runtime error of invalid dont_send value

Browse Source 
Oss-fuzz complains that (struct user_action_cookie)->controller->dont_send
has invalid vlue, like below:
runtime error: load of value 26, which is not a valid value for type 'bool'

From this piece of code "cookie.controller.dont_send ? 1 : 0", it looks
like that we want to tolerate values than 0 and 1.

Thus, this patch changes the types of dont_send and continuation from bool
to uint8_t in order to make oss-fuzz happy.
