[ Upstream commit e4b019515f950b4e6e5b74b2e1bb03a90cb33039 ]
Right now Linux BT stack cannot pass test case "GAP/CONN/CPUP/BV-05-C
'Connection Parameter Update Procedure Invalid Parameters Central
Responder'" in Bluetooth Test Suite revision GAP.TS.p44. [0]
That was revoled by commit c49a8682fc5d ("Bluetooth: validate BLE
connection interval updates"), but later got reverted due to devices
like keyboards and mice may require low connection interval.
So only validate the max value connection interval to pass the Test
Suite, and let devices to request low connection interval if needed.

[ Upstream commit 96a3398b467ab8aada3df2f3a79f4b7835d068b8 ]
In case of an incomplete command or a command with a null identifier 2
reject packets will be sent, one with the identifier and one with 0.
Consuming the data of the command will prevent it.
This allows to send a reject packet for each corrupted command in a
multi-command packet.

commit 78b99eb1faa7371bf9c534690f26a71b6996622d upstream.
L2CAP/COS/CED/BI-02-C PTS test send a malformed L2CAP signaling packet
with 2 commands in it (a connection request and an unknown command) and
expect to get a connection response packet and a command reject packet.
The second is currently not sent.
