Resend remaining VMAs on partial compaction due to failure

process_madvise syscall returns the total bytes that were processed
however, upon failure it will send the partial amount of bytes
that were processed in which case this patch aims to skip the failure
page then resend any batch of vmas that was not fully processed.
This way we would effectively process the whole range of vmas
rather than skipping the rest of the vmas in batch when
process_madvise does a partial advise.
