[PATCH 07/23] agp/nvidia: Use the dma_addr[] instead of page_to_phys when inserting.

[Konrad Rzeszutek Wilk]

The dma_addr contains the same value as page_to_phys(page). That is
until the PCI API is enabled at which point the dma_addr will
contain the true DMA (bus) address - which on baremetal will in all
likehood be the same as page_to_phys(page). But under Xen it might
be different.
