uvadapter: reduce number of uv_poll_start calls

Browse Source 
Internally uv_poll_start iterates over all
attached event handlers to update event mask. It's
quite expensive operation if there many event handlers attached
to a loop.
As redisLibuvEvents.events is a copy of what libuv should see,
we can rely on it to avoid event mask updates.
