[MINOR] Minior fixes in lineage cache eviction.

This patch removes a bug where we were making space after
putting an entry in the cache -- this can evict the current
entry and introduce memory leak. Now we make space before
adding an entry to cache. Furthermore, this patch increases
the default I/O speed values to enable early starting of
spilling. The rolling adjustment logic anyway updates
the speed values according to the disk.
