qcacld-2.0: Wake TX queues before waking up the target when wlan resumes
In WoW mode, when TX queues are woken up after waking up the target,
the buffered packets in firmware are received immediately. For certain
packets like ping request the response is sometimes sent immediately
before TX queues are woken up. This is because the waking up of target
happens from process context (PM resume) while the packet is received
in interrupt context. The processing of received packet and response
takes priority here and by the time the ping response is sent TX queues
are still disabled. So the ping responses are dropped. To fix this,
wake up the TX queues before sending the wake up WMI command to target.
