qcacld-3.0: Change the timer call from qdf_timer_start to qdf_timer_mod

In hdd_bus_bw_work_handler() change the timer call from
qdf_timer_start to qdf_timer_mod as following race condition
could be possible:
1. Softirq fires and schedules the delayed work,
2. Disconnect reconnect occurs and timer gets stopped and
   started from mc thread, and
3. The delayed work tries to do the add timer and kernel BUG ON
   because the timer is already running.
