mm: remove lru parameter from __lru_cache_add and lru_cache_add_lru

Browse source 
Similar to __pagevec_lru_add, this patch removes the LRU parameter from
__lru_cache_add and lru_cache_add_lru as the caller does not control the
exact LRU the page gets added to.  lru_cache_add_lru gets renamed to
lru_cache_add the name is silly without the lru parameter.  With the
parameter removed, it is required that the caller indicate if they want
the page added to the active or inactive list by setting or clearing
PageActive respectively.
