Bluetooth: hci_bcsp: validate received packet lengths

The BCSP transmit path reads an HCI command header when an extension
packet has only been tested for a nonzero length. Its LE configuration
packet handler also indexes bytes through offset seven without a length
check.

Validate the complete command and LE configuration packet headers
before accessing their fields.
