x86, cleanup: kexec memory range .end to be inclusive
Later kexec and kdump memory range will be mapped to E820entry. But
currently kexec memory range .end field is exclusive while crash memory
range is inclusive.
Given the fact that the exported proc iomem and sysfs memmap are both
inclusive, change kexec memory range .end to be inclusive. Later the
unified memory range of both kexec and kdump can use the same E820
filling code.
