Subject: [PATCH] entry: Fix ifndef around
 arch_xfer_to_guest_mode_handle_work() stub

The stub implementation of arch_xfer_to_guest_mode_handle_work() is
guarded by an #ifndef that incorrectly checks for the name
arch_xfer_to_guest_mode_work instead. It seems the function was renamed
to add "_handle" as a late change to the original patch, and the #ifndef
wasn't updated to go with it.

Change the #ifndef to match the name of the function. No users right now,
so no need to update the arch code.

Fixes: 935ace2fb5cc4 ("entry: Provide infrastructure for work before transitioning to guest mode")
