Closes https://github.com/espressif/esp-idf/issues/9398
For the CID10564,10384,10280,10098,10038,The memory was released in other place.
For the CID10365,it release the memory in the function when sent successfully.
For the CID10268,10011, we need not change the code.
Added BD_ADDR comparison in l2cu_lcp_allocate and removed check from
security connection request handler as it's handled in l2cu_lcp_allocate
for both connection request and create connection.
There was no need for this function as there is already a way present to
fetch own mac address. Own mac addr can be fetched by calling
controller_get_interface().
Prevent a remote device from doing a Bluetooth Impersonation Attack
(BIAS) by:
- Preventing remote device to downgrade secure connection
feature mask. Secure connection feature mask should remain same or
increase to enabled in link key generation and authentication.
- Doing a mutual authentication during Legacy Authentication.
