qcacld-3.0: Increase timeout for vdev_del_event

Browse Source 
Race condition occurred as rx_thread did not get scheduled
before timeout and gro flush happened in vdev context. At
the same time, rx thread got scheduled and add skb to the
napi queue resulting in crash.
To fix this, Increase the timeout value so rx_thread gets
time to wake up, do gro flush and reset the vdev_del_event.
