Subject: [PATCH] entry: KVM: Change override for arch_xfer_to_guest_mode_handle_work()

Change the way arch_xfer_to_guest_mode_handle_work() can be overridden
by architecture code. Use the function name as the preprocessor define.
This is better greppable. And it resembles the way many other overrides
are constructed in the tree.

Note that none of this matters at the moment. There is no architecture
overriding this function. This change is purely cosmetic.
