Bluetooth: Fix accepting connect requests for defer_setup

When authentication completes we shouldn't blindly accept any pending
L2CAP connect requests. If the socket has the defer_setup feature
enabled it should still wait for user space acceptance of the connect
request. The issue only happens for non-SSP connections since with SSP
the L2CAP Connect request may not be sent for non-SDP PSMs before
authentication has completed successfully.
