[PATCH v4 5/8] Bluetooth: Fix L2CAP error return used for failed channel lookups

[johan.hedberg@gmail.com]

From: Johan Hedberg <johan.hedberg@intel.com>

The EFAULT error should only be used for memory address related errors
whereas ENOENT should be used for failed lookups for the given CID. This
patch fixes the l2cap_connect_create_rsp and l2cap_create_channel_req
handlers to use the correct ENOENT error return.
