epoll: avoid kmemcheck warning
Epoll calls rb_set_parent(n, n) to initialize the rb-tree node, but rb_set_parent() accesses node's pointer in its code. This creates a warning in kmemcheck (reported by Vegard Nossum) about an uninitialized memory access. The warning is harmless since the following rb-tree node insert is going to overwrite the node data. In any case I think it's better to not have that happening at all, and fix it by simplifying the code to get rid of a few lines that became superfluous after the previous epoll changes.
