When removing inactive queue - use the central disable queue
function. This is needed due to a000 changes to come, but is
a proper cleanup anyway.

In v2:
iwl_mvm_disable_txq() returns early if the hw_ref_count is
zeroed, with the result of the queue not being properly disabled.
Avoid zeroing it and other queue information in remove_sta_marking().
iwl_mvm_disable_txq() which is called later in the flow will zero
it.
