Andrey Ryabinin b1da22af26 ARM: 8051/1: put_user: fix possible data corruption in put_user ...

commit 537094b64b upstream.

According to arm procedure call standart r2 register is call-cloberred.
So after the result of x expression was put into r2 any following
function call in p may overwrite r2. To fix this, the result of p
expression must be saved to the temporary variable before the
assigment x expression to __r2.
