staging: wilc1000: give usleep_range a range
usleep_range() is called in non-atomic context so there is little point in setting min==max as the jitter of hrtimer is determined by interruptions anyway. usleep_range can only perform the intended coalescence if some room for placing the hrtimer is provided. Given the range of milliseconds the delay will be 2+ anyway - so make it 2-2.5 ms which gives hrtimers space to optimize without negatively impacting performance.
