ntfs: remove unnecessary PG_uptodate check from ntfs_readpage

[Pekka J Enberg <penberg@cs.Helsinki.FI>]

From: Pekka Enberg <penberg@cs.helsinki.fi>

The check is not needed because SetPageUptodate is called for locked pages
and callers of ->readpage either explicitly check for PageUptodate or pass
newly allocated pages (see read_cache_pages and page_cache_read).
