[PATCH] x86/xen: remove redundant variable save_pud

From: Colin King
Date: Tue Aug 28 2018 - 12:11:04 EST


From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

Variable save_pud is being assigned but is never used hence it is
redundant and can be removed.

Cleans up clang warning:
variable 'save_pud' set but not used [-Wunused-but-set-variable]
