kdump: check flags field from drconf memory

On a powerpc machine when memory is dynamically removed/added from an lpar, the
corresponding flags field in the drconf memory reflects the same with the bits
unset/set accordingly. The kernel does a check on these flags while booting.
Following are the similar changes brought in to kexec-tools.  This makes
kexec-tools to skip those memory regions that do not belong or are not
assigned to the current partition ( but are available to dynamically add them
back ). Without this patch (and with memory remove operation) copying vmcore
fails with error as

Copying data                       : [ 84 %] readmem: Can't read the dump
memory(/proc/vmcore). Bad address
read_pfn: Can't get the page data.
