Subject: [net-2.6 PATCH] igbvf: fix issue w/ mapped_as_page being left set
	after unmap

From: Alexander Duyck <alexander.h.duyck@...el.com>

This change fixes an issue in igbvf with mapped_as_page being left set
after a page is unmapped which results in buffers which are mapped via map
single being unmapped as page.
