x86/uaccess: Add unlikely() to __chk_range_not_ok() failure paths
This should improve code quality a bit. It also shrinks the kernel text:
Before:
text data bss dec filename
21828379 5194760 1277952 28301091 vmlinux
After:
text data bss dec filename
21827997 5194760 1277952 28300709 vmlinux
... by 382 bytes.
