    Revert "bpf: Take return from set_memory_ro() into account with bpf_prog_lock_ro()"
    
    This reverts commit fdd411af8178edc6b7bf260f8fa4fba1bedd0a6d which is
    commit 7d2cc63eca0c993c99d18893214abf8f85d566d8 upstream.
    
    It is part of a series that is reported to both break the arm64 builds
    and instantly crashes the powerpc systems at the first load of a bpf
    program.  So revert it for now until it can come back in a safe way.
