Fix: backported from urcu commit 92af1a30

    Fix undefined NULL pointer arithmetic

    Clang 3.3 with -O2 optimisations is especially picky about arithmetic
    on NULL pointers. This undefined behavior is turned into optimized out
    NULL checks by clang 3.3. Fix the undefined behavior by checking against
    the pointer directly, without going back and forth around NULL with
    pointer arithmetic.
