wifi: iwlwifi: mvm: fix the TLC command after ADD_STA

Browse Source 
[ Upstream commit 0fcdf55fced7121c43fa576433986f1c04115b73 ]

ADD_STA resets the link quality data inside the firmware. This is not
supposed to happen and has been fixed for newer devices. For older
devices (AX201 and down), this makes us send frames with rates that are
not in the TLC table.
