[PATCH] x86/hvm: reserve another HVM context save record ID for Amazon

[David Vrabel <dvrabel@xxxxxxxxxx>]

Amazon's guest transparent live migration work needs another save
record (for event channel upcall vectors). Reserve another HVM context
save record ID for this.

I've added it to the end, keeping the unused ID at 21.
