code-style: simplify some checks
main change here is making the `zoom()` logic saner. the rest of the changes are just small stuff which accumulated on my local branch. pop() must not be called with NULL. and `zoom()` achieves this, but in a very (unnecessarily) complicated way: if c == NULL then nexttiled() will return NULL as well, so we enter this branch: if (c == nexttiled(selmon->clients)) in here the !c check fails and the function returns before calling pop() if (!c || !(c = nexttiled(c->next))) return; however, none of this was needed. we can simply return early if c was NULL. Also `c` is set to `selmon->sel` so we can use `c` in the first check instead which makes things shorter.
