Having a single HCI_ADVERTISING flag is problematic since it tries to

An AP/GO may perform the channel switch slightly before its stations.
This scenario may result in packet loss, since the transmission may start
before the client is actually on a new channel. In order to prevent
potential packet loss disable tx to all the stations when the channel
switch flow starts. Clear the disable_tx bit when a station is seen on a
target channel, or after IWL_MVM_CS_UNBLOCK_TX_TIMEOUT beacons on a new

It turns out that adding the update type argument was pointless as
quota update is never called from the add_interface() callback.
Therefore, IWL_MVM_QUOTA_UPDATE_TYPE_NEW isn't actually needed and
then only a "disabled_vif" argument is needed for the upcoming CSA
work.
