iwlwifi: mvm: update BAID allocation command again

Due to some issues found in integration, the command now has
the (old) station mask and TID in modify/remove instead of
the BAID, adjust accordingly.

Since we don't use modify yet (and never will with v1 of the
API), just add v1 remove inside the existing union, and use
that, this way we don't have to duplicate everything, only
the remove code.
