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.
