When kexec-tools load the kernel and initramfs for kdump, kexec-tools will
read /proc/iomem and recreate the e820 ranges for kdump kernel. But it fails
to parse the e820 reserved region, because the memcmp() is case sensitive
when comparing the string. In fact, it may be "Reserved" or "reserved" in
the /proc/iomem, so we use the strncasecmp() instead of the memcmp() to fix
it.
