[PATCH] Fix memory leak in epoll

There was a memory leak in epoll.

The reference count (d_count) of the struct dentry of a new epoll-fd was
set to TWO.  (new_inode() assigned ONE, than ep_getfd() incremented it by
dget()).  There was only ONE reference to this dentry, so struct dentry and
struct inode were never freed.
