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. Here is the
hcidump:

Error: Connection Accept Timeout Exceeded
With this patch we will retry with a SCO connection, which succeeds.
Unfortunately the Moto HF850 also takes 5 seconds to return the error for the
eSCO attempt, so it will still take 5 seconds to fallback to SCO with this
patch.
