Subject: [PATCH] kernel/wait_for_objects: Fix copy/paste error in poll().

Seems none of the applications I tested yesterday actually used poll(),
because it was completely broken by this.

The previous code assigned this variable inside a malloc() call, though,
which wasn't all that obvious either.
