qcacld-3.0: Cleanup current peers upon secondary STA roaming

The secondary STA is non-ML type by default, so driver doesn't
create mld/ml_dev_ctx for the vdev corresponds to secondary
interface which is wlan1.

But in current scenario there is a check in the peer cleanup
API which always expects ml_dev_ctx. when secondary STA(wlan1)
roams from one AP to other AP, driver doesn't cleanup the old
peer due to this check and results a peer leak.

Delete all peers even when secondary STA roaming which avoid
this issue.
