Kumar Kartikeya Dwivedi 67d9e6b250 selftests/bpf: Make linked_list failure test more robust
[ Upstream commit da1055b673 ]

The linked list failure test 'pop_front_off' and 'pop_back_off'
currently rely on matching exact instruction and register values.  The
purpose of the test is to ensure the offset is correctly incremented for
the returned pointers from list pop helpers, which can then be used with
container_of to obtain the real object. Hence, somehow obtaining the
information that the offset is 48 will work for us. Make the test more
robust by relying on verifier error string of bpf_spin_lock and remove
dependence on fragile instruction index or register number, which can be
affected by different clang versions used to build the selftests.
