Add a check that the buffer is large enough to hold the fixed struct and the num_msg variable-length entries. The `ath6kl_wmi_tx_complete_event_rx()` function, responsible for handling Wi-Fi messages, does not properly validate the `num_msg` field provided by the firmware against the buffer length.
