[PATCH v3] binder: remove redundant variable page_addr

[Carlos Llamas]

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]

Signed-off-by: Colin Ian King <colin.i.king@xxxxxxxxx>
Fixes: 162c79731448 ("binder: avoid user addresses in debug logs")
Reported-by: kernel test robot <lkp@xxxxxxxxx>
Closes: https://lore.kernel.org/oe-kbuild-all/202312060851.cudv98wG-lkp@xxxxxxxxx/
Acked-by: Carlos Llamas <cmllamas@xxxxxxxxxx>

Notes:
    v2: added tags, used char-misc-next as base
    v3: rebased, fixed conflicts with 0a97c01cd20b
