arm64: ptdump: Fix format output during pagetable parsing

Fix an issue where the output range printed to debugfs was no showing
out correctly. If the st->start_address was larger than the current
addr the delta variable calculated as delta = addr - st->start_address
used to display the size of the address range will overflow. This leads
to wrong printed values to debugfs when someone tries to read from the
host_stage2_kernel_page_tables.
