Bluetooth: Fallback to SCO on error code 0x10 (Connection Accept Timeout)

Bluetooth: Fallback to SCO on error code 0x10 (Connection Accept Timeout)

This is to support the Motorola HF850 carkit which reports the error
code 0x10 for an eSCO attempt, even though it advertises eSCO support.

With this patch we will retry with a SCO connection, which succeeds.
