Byungchul Park 54cf41c969 Revert "mm: introduce a new page type for page pool in page type" 
This reverts commit db359fccf2 ("mm: introduce a new page type for page
pool in page type") and a part of 735a309b4b ("net: add net_iov_init()
and use it to initialize ->page_type").

Netpp page_type'ed pages might be used in mapping so as to use @_mapcount.
However, since @page_type and @_mapcount are union'ed in struct page,
these two can't be used at the same time.  Revert the commit introducing
page_type for Netpp for now.

The patch will be retried once @page_type and @_mapcount get allowed to be
used at the same time.

The revert also includes removal of @page_type initialization part
introduced by commit 735a309b4b ("net: add net_iov_init() and use it
to initialize ->page_type"), which will be restored on the retry.
