LE: UPF 45 bug fixes

This change fixes the following issues:
- Second GATT-over-BR/EDR channel cannot be established when there
  already is an existing GATT-over-BR/EDR channel
- If encryption fails for an LE connection due to a missing key,
  the security state is not being cleared and blocks all further
  security processing
- When DM discovery of an LE Peripheral device fails with a
  connection timeout, no further discovery requests can be made
- GATT service discovery can get into endless loop when duplicate descriptor
  definitions are found on the remote device
- When GATT over BR/EDR fails, BTA does not give a connection
  callback to the application initiating the connection
- BR/EDR connection to remote platform does not generate API callbacks
- Stack crash discovered during UPF after remote disconnects
- The host is sending HCI disconnect to invalid HCI handle when
  SMP fails because of a connection timeout
- Possible race condition:
  If a disconnect is immediately followed by a connection complete,
  the connection complete cannot be processed in the BTA GATT state
  machine
- Write Complete event is not triggered for Prepare Write requests
