Kees Cook 6787d3ecbe ARM: 8658/1: uaccess: fix zeroing of 64-bit get_user() 
commit 9e34404818 upstream.

The 64-bit get_user() wasn't clearing the high word due to a typo in the
error handler. The exception handler entry was already correct, though.
Noticed during recent usercopy test additions in lib/test_user_copy.c.
