wifi: ath12k: ath12k_mac_vdev_create(): use goto for error handling

In commit 477cabfd ("wifi: ath12k: modify link arvif creation and removal
for MLO") I had accidentally left one personal TODO comment about using goto
instead of ret. Switch to use goto to be consistent with the error handling in
the function.
