[PATCH v2] binder: remove redundant variable page_addr

From: Carlos Llamas
Date: Tue Jan 16 2024 - 14:32:59 EST


From: Colin Ian King <colin.i.king@xxxxxxxxx>

Variable page_addr is being assigned a value that is never read. The
variable is redundant and can be removed.

Cleans up clang scan build warning:
warning: Value stored to 'page_addr' is never read [deadcode.DeadStores]

Closes: https://lore.kernel.org/oe-kbuild-all/202312060851.cudv98wG-lkp@xxxxxxxxx/
