coccinelle: Extend address test from ifaddr semantic patch to test expressions
The test of an expression's address does not necessarily represent the whole condition, it may only be a part of it. Also, an expression's address is likely to be non-zero in every test expression, not only in if statements. This change aims at detecting an address test in more complex conditions and not only in if statements.
