staging: vchiq_2835_arm: Fix NULL ptr dereference in free_pagelist
commit 974d4d03fc020af4fa4e9e72a86f0fefa37803c5 upstream.
This fixes a NULL pointer dereference on RPi 2 with multi_v7_defconfig.
The function page_address() could return NULL with enabled CONFIG_HIGHMEM.
So fix this by using kmap() instead.
