    nvmm: Improve nvmm_return_needed() by using nvmm_break_wanted()
    
    Use the newly added nvmm_break_wanted() routine to check for pending
    host events, improving nvmm_return_needed().  Just stuff
    nvmm_break_wanted() into nvmm_return_needed() and get rid of
    preempt_needed(), making the code clearer.
    
    Also add __predict_false() macro to help performance a bit.
