[PATCH 5.19 0764/1157] mm: rmap: use the correct parameter name for DEFINE_PAGE_VMA_WALK

[Greg Kroah-Hartman]

From: Yang Shi <shy828301@xxxxxxxxx>

[ Upstream commit 507db7927cd181d409dd495c8384b8e14c21c600 ]

The parameter used by DEFINE_PAGE_VMA_WALK is _page not page, fix the
parameter name.  It didn't cause any build error, it is probably because
the only caller is write_protect_page() from ksm.c, which pass in page.
