io_napi_entry() has 2 calling sites. One of them is unlikely to find an
entry and if it does, the timeout should arguable not be updated.

The other io_napi_entry() calling site is overwriting the update made
by io_napi_entry() so the io_napi_entry() timeout value update has no or
little value and therefore is removed.
