Daniel Borkmann 2746d3face bpf, selftests: Update test case for atomic cmpxchg on r0 with pointer
commit e523102cb719cbad1673b6aa2a4d5c1fa6f13799 upstream.

Fix up unprivileged test case results for 'Dest pointer in r0' verifier tests
given they now need to reject R0 containing a pointer value, and add a couple
of new related ones with 32bit cmpxchg as well.
