wifi: iwlwifi: mvm: allocate STA links only for active links

Browse Source 
[ Upstream commit 62bdd97598 ]

For the mvm driver, data structures match what's in the firmware,
we allocate FW IDs for them already etc. During link switch we
already allocate/free the STA links appropriately, but initially
we'd allocate them always. Fix this to allocate memory, a STA ID,
etc. only for active links.
