Bluetooth: hci_sync: Fix not setting mask for HCI_EVT_LE_ALL_REMOTE_FEATURES_COMPLETE

This fixes not setting the bit for HCI_EVT_LE_ALL_REMOTE_FEATURES_COMPLETE
when extended features bit is set otherwise the controller may not
generate HCI_EVT_LE_ALL_REMOTE_FEATURES_COMPLETE causing
hci_le_read_all_remote_features_sync to timeout waiting for it.

Also remove dead code.
