Sara Sharon 9b137866f9 iwlwifi: mvm: save low latency causes in an enum 
Currently we have a boolean variable for each cause.

This costs space, and requires to check each separately
when determining low latency.

Since we have another cause incoming, convert it to an enum.

While at it, move the retrieval of the prev value and the
assignment of the new value to be inside iwl_mvm_update_low_latency
and save the need for each caller to do it separately.

* This is the state of a queue that has been fully configured (including
* SCD pointers, etc), has a specific RA/TID assigned to it, and can be
* used to send traffic.
* @IWL_MVM_QUEUE_SHARED: queue is shared, or in a process of becoming shared
* This is a state in which a single queue serves more than one TID, all of
* which are not aggregated. Note that the queue is only associated to one
* RA.
* @IWL_MVM_QUEUE_INACTIVE: queue is allocated but no traffic on it
* This is a state of a queue that has had traffic on it, but during the
* last %IWL_MVM_DQA_QUEUE_TIMEOUT time period there has been no traffic on
* it. In this state, when a new queue is needed to be allocated but no
* such free queue exists, an inactive queue might be freed and given to
* the new RA/TID.
* @IWL_MVM_QUEUE_RECONFIGURING: queue is being reconfigured
* This is the state of a queue that has had traffic pass through it, but
* needs to be reconfigured for some reason, e.g. the queue needs to
* become unshared and aggregations re-enabled on.
