mm/khugepaged.c: fix khugepaged's request size in collapse_file
commit e5a59d308f52bb0052af5790c22173651b187465 upstream.
collapse_file() in khugepaged passes PAGE_SIZE as the number of pages to
be read to page_cache_sync_readahead(). The intent was probably to read
a single page. Fix it to use the number of pages to the end of the
window instead.
