build_mem_phdrs(): check if p_paddr is invalid
Currently, all the p_paddr of PT_LOAD headers are assigned to 0, which
is not correct and could be misleading, since 0 is a valid physical
address.
Upstream kernel commit "464920104bf7 /proc/kcore: update physical
address for kcore ram and text" fixed it and now invalid PT_LOAD is
assigned as -1.
kexec/arch/i386/crashdump-x86.c:get_kernel_vaddr_and_size() uses kcore
interface and so calls build_mem_phdrs() for kcore PT_LOAD headers.
This patch fixes build_mem_phdrs() to check if p_paddr is invalid.
