Fixed a warning about comma misuse

[MonkeybreadSoftware]

I build my stuff with a lot of checks and warnings.
So I got this one, where clang complains about the comma misuse.
Why is f initialized in the for and not just before?
Unless there is some special real, I'd like to move it up.

.../curl-test/curl/lib/easy.c:568:21: warning: possible misuse of comma operator here [-Wcomma]
  568 |     for(m = ev->list, f = &fds[0]; m; m = m->next) {
      |                     ^
.../curl-test/curl/lib/easy.c:568:9: note: cast expression to void to silence warning
  568 |     for(m = ev->list, f = &fds[0]; m; m = m->next) {
      |         ^~~~~~~~~~~~
      |         (void)(     )
