Don't require A2DP codec information when initialize audio_hal_interface

Before set active device, it is normal that can't get the current codec
information, and will be setup later. If we query the codec and break
the init, it will cause the stack can't use Bluetooth Audio HAL for
A2DP, so remove here.

Test: Connect / disconnect multiple A2DP manually when playing
