[PATCH] x86: uaccess: return value of __{get|put}_user() can be int

[Hiroshi Shimamoto <h-shimamoto@ct.jp.nec.com>]

From: Hiroshi Shimamoto <h-shimamoto@ct.jp.nec.com>

Impact: cleanup

The type of return value of __{get|put}_user() can be int.
There is no user to refer the return value of __{get|put}_user() as long.
This reduces code size a bit on 64-bit.
