qcacld-3.0: Wait for download complete only when OTA required

qcacld-2.0 to qcacld-3.0 propagation

Currently for low latency target, host is waiting for 1 sec for download
complete, which is blocking MC thread. Due to this MC thread is not
serving the SME queue and which triggers the active cmd time out.

As a part of this fix, MC thread waits for download complete only
for those frame which needs OTA.
