kexec: fix /sys/firmware/memmap memory range overlaps
The memory ranges derived from /sys/firmware/memmap may overlap, causing
the kexec command to fail to load the crash kernel. The typical failure
reports 'Overlapping memory segments at 0x...'.
The preferred remedy might be to fix the BIOS or the kernel, but given
that they may at times generate overlaps, a check in the kexec command
will prevent crash dumps from being effectively disabled.
