[PATCH] x86/sev: clean up initialization of variables info and v

From: Colin Ian King
Date: Fri Nov 26 2021 - 17:39:05 EST


Currently variable info is being assigned twice, the second assignment
is redundant. Clean up the code by making the assignments at declaration
time and remove the latter two assignments.
