qcacld-3.0: Init the thread resume wait event before setting suspend event

qcacld-2.0 to qcacld-3.0 propagation

While suspending threads suspend complete event is set before
resume wait event is initialized.

In case resume is followed by suspend there might arise a condition
where resume wait event is set even before its initialization.
Thus after initializing the wait event thread will keep on waiting
on the event and thus get stuck.

To avoid this initialize the thread resume wait event before
setting the suspend event.
