Bluetooth: MGMT: reject malformed HCI_CMD_SYNC commands
In 'mgmt_hci_cmd_sync()', check whether the size of parameters passed
in 'struct mgmt_cp_hci_cmd_sync' matches the total size of the data
(i.e. 'sizeof(struct mgmt_cp_hci_cmd_sync)' plus trailing bytes).
Otherwise, large invalid 'params_len' will cause 'hci_cmd_sync_alloc()'
to do 'skb_put_data()' from an area beyond the one actually passed to
'mgmt_hci_cmd_sync()'.
