arm64: start using 'asm goto' for put_user()
This generates noticeably better code since we don't need to test the
error register etc, the exception just jumps to the error handling
directly.
Unlike get_user(), there's no need to worry about old compilers. All
supported compilers support the regular non-output 'asm goto', as
pointed out by Nathan Chancellor.
