Bluetooth: ISO: Fix not checking for valid CIG/CIS IDs

[ Upstream commit b7f923b ] Valid range of CIG/CIS are 0x00 to 0xEF, so this checks they are properly checked before attempting to use HCI_OP_LE_SET_CIG_PARAMS. Fixes: ccf74f2 ("Bluetooth: Add BTPROTO_ISO socket type") Signed-off-by: Luiz Augusto von Dentz <[email protected]> Signed-off-by: Sasha Levin <[email protected]>
