Bluetooth: Fix invalid length check in l2cap_information_rsp()

commit 3f6fa3d489e127ca5a5b298eabac3ff5dbe0e112 upstream.

The length check is invalid since the length varies with type of
info response.

This was introduced by the commit cb3b3152b2f5939d67005cff841a1ca748b19888

Because of this, l2cap info rsp is not handled and command reject is sent.
