tipc: split variable assignments out of conditional expressions
Cleans up TIPC's source code to eliminate assigning values to variables within conditional expressions, improving code readability and reducing warnings from various code checker tools. These changes are purely cosmetic and do not alter the operation of TIPC in any way.
