ieee80211_alloc_hw_nm will validate the requested name (if any) before creating the new device and may use a name different from the one requested rather than fail. Make sure the HWSIM_CMD_NEW_RADIO event/response generated has the final name or userspace will receive the wrong name. Note that mac80211_hwsim_new_radio may now modify params.
A check for duplicate radio name could be added separately.
