[PATCH] x86/sev: remove duplicated assignment to variable info

From: Colin Ian King
Date: Mon May 16 2022 - 14:42:22 EST


Variable info is being assigned the same value twice, remove the
redundant duplicate. Also assign variable v in the declaration.

Cleans up clang scan warning:
warning: Value stored to 'info' during its initialization is never
read [deadcode.DeadStores]
