Bluetooth: hci_sync: Fix not setting CE length properly
Both hci_le_set_def_rate_sync() and hci_le_conn_rate_request_sync() were
leaving Min_CE_Length and Max_CE_Length set to 0x0000, but the connection
event length recommended in requests by a Peripheral has a valid range of
0x0001 to 0x7CFF (Time = N * 125 us, Time Range: 0.125 ms to 3.999875 s),
so 0x0000 cannot be used.
Set both to the minimum valid value, which is safe since the Controller
is not required to use these values:
BLUETOOTH CORE SPECIFICATION Version 6.2 | Vol 4, Part E
7.8.157. LE Connection Rate Request command
7.8.158. LE Set Default Rate Parameters command
The Min_CE_Length and Max_CE_Length parameters provide the Controller
with the expected minimum and maximum length of the connection events.
The Controller is not required to use these values.
Fixes: 2f8784cfe8a9 ("Bluetooth: Add support for Shorter Connection Interval (SCI) feature")
