HFP: Fix reading multiple AT commands from a single data packet

Browse Source 
The `data` received in `_read_at` may have multiple commands.

This fixes `execute_command` timing out when waiting for an `OK`
response when it is in the same data buffer, e.g. during SLC
initialization: b'\r\n+BRSF: 3904\r\n\r\nOK\r\n'
