Bluetooth: hci_sync: Fix using the same interval and window for Coded PHY

[ Upstream commit 53cb4197 ]

Coded PHY recommended intervals are 3 time bigger than the 1M PHY so
this aligns with that by multiplying by 3 the values given to 1M PHY
since the code already used recommended values for that.

Fixes: 288c9022 ("Bluetooth: Enable all supported LE PHY by default")
