[PATCH] mm: double mark_page_accessed() in read_cache_page_async()

[Peter Zijlstra <peterz@infradead.org>]

read_cache_page_async() seems to have two invocations of
mark_page_accessed() which will launch pages right onto the active list.

Remove the first one, keeping the latter one. This avoids marking
unwanted pages active (in the retry loop).
