Bluetooth: L2CAP: Fix errors during L2CAP_CREDIT_BASED_CONNECTION_REQ (0x17)
Fix 2 typos in L2CAP_CREDIT_BASED_CONNECTION_REQ (0x17) handling function, that
cause BlueZ answer with L2CAP_CR_LE_INVALID_PARAMS or L2CAP_CR_LE_INVALID_SCID
error on a correct ECRED connection request.
Enchanced Credit Based Mode support was recently introduced with the commit
15f02b91056253e8cdc592888f431da0731337b8 ("Bluetooth: L2CAP: Add initial code
for Enhanced Credit Based Mode").
