Luiz Augusto von Dentz 935f324e4b Bluetooth: L2CAP: Fix result of L2CAP_ECRED_CONN_RSP when MTU is too short 
[ Upstream commit c28d2bff70 ]

Test L2CAP/ECFC/BV-26-C expect the response to L2CAP_ECRED_CONN_REQ with
and MTU value < L2CAP_ECRED_MIN_MTU (64) to be L2CAP_CR_LE_INVALID_PARAMS
rather than L2CAP_CR_LE_UNACCEPT_PARAMS.

Also fix not including the correct number of CIDs in the response since
the spec requires all CIDs being rejected to be included in the
response.
