x86: clean up max_pfn_mapped usage - 32-bit

on 32-bit in head_32.S after initial page table is done, we get initial
max_pfn_mapped, and then kernel_physical_mapping_init will give us
a final one.

We need to use that to make sure find_e820_area will get valid addresses
for boot_map and for NODE_DATA(0) on numa32.

XEN PV and lguest may need to assign max_pfn_mapped too.
