    x86/qspinlock: Fix compile error · b987ffc1

    With a compiler that has asm-goto but not asm-cc-output and
    CONFIG_PROFILE_ALL_BRANCHES=y we get a compiler error:
    
      arch/x86/include/asm/rmwcc.h:23:17: error: jump into statement expression
    
    Fix this by writing the if() as a boolean multiplication instead.
