    selftests/net: psock_fanout seg faults in sock_fanout_read_ring()

    The while loop in sock_fanout_read_ring() checks mmap region
    bounds after access, causing it to segfault. Fix it to check
    count before accessing header->tp_status. This problem can be
    reproduced consistently when the test in run as follows:

        make -C tools/testing/selftests TARGETS=net run_tests
        or
        make run_tests from tools/testing/selftests
        or
        make run_test from tools/testing/selftests/net
