This reverts commit 0549a3c02e ("kdump, vmcoreinfo: report memory
sections virtual addresses").
Commit 0549a3c02e tells the userspace utility makedumpfile the
randomized base address of these memmory sections when mm kaslr is
enabled. However the following patch "kexec: export the value of
phys_base instead of symbol address" makes makedumpfile not need these
addresses any more.
Besides we should use VMCOREINFO_NUMBER to export the value of the
variable so that we can use the existing number_table mechanism of
Makedumpfile to fetch it. So revert it now. If needed we can add it
later.
