Comment:

 I have clarified the code, calling the new function
 `should_remove_intro_point()` and simplified the logic.

 The code works this way:

 If this statement is true:

 {{{
     if (ip->circuit_established || hs_circ_service_get_intro_circ(ip))
 }}}

 We return `false` to not destroy the circuit. Otherwise, we return this
 test case:

 {{{
   return (ip->circuit_retries > MAX_INTRO_POINT_CIRCUIT_RETRIES);
 }}}

 Setting as needs review.
