[PATCH 1/2] Submit physical address to is_phys_addr()

ELF program table virtual address is submitted to is_phys_addr()
function, most likely as a leftover of replaced is_vmalloc_addr()
function. Submit the physical address instead.

This fixes the below error when CONFIG_RANDOMIZE_IDENTITY_BASE
kernel configuration option on s390 is enabled:

get_kcore_dump_loads: Can't get the correct number of PT_LOAD. Success

Fixes: 2e452d75fa78 ("[PATCH v3] Enable --mem-usage for s390x.")
