Currently, is_kdump_kernel() returns true when elfcorehdr_addr is set. While elfcorehdr_addr is set for kexec based kernel dump mechanism, alternate dump capturing methods like fadump [1] also set it to export the vmcore. Since, is_kdump_kernel() is used to restrict resources in crash dump capture kernel and such restrictions may not be desirable for fadump, allow is_kdump_kernel() to be defined differently for such scenarios. With this, is_kdump_kernel() could be false while vmcore is usable. So, remove unnecessary dependency with is_kdump_kernel(), for exporting vmcore.
