qcacld-3.0: Avoid checking for netif queues unpause in Data flow control when in Reassociating state

propagation from qcacld-2.0 to qcacld-3.0

During re-association, host does not enable the netif queues
and does not reset the pause bit map from Data flow control
if queues are already paused due to lack of enough descriptors
which is not correct and lead to disconnection.
Host has now centralised mechanism to pause/unpause netif queues
using bitmap, so there is no need to keep the netif queues in paused
state from data flow control path.
To fix this, remove the tx queue unpause check when in reassociation
state.
