Andrew Earl 27539bc441 Bluetooth: Fix aborting eSCO connection in case of error 0x20
Add additional error case to attempt alternative configuration for SCO. Error
occurs with Intel BT controller where fallback is not attempted as the error
0x20 Unsupported LMP Parameter value is not included in the list of errors
where a retry should be attempted.
The problem also affects PTS test case TC_HF_ACS_BV_05_I.

See the HCI log below for details:
