svc: Remove unnecessary call to svc_sock_enqueue

The svc_tcp_accept function calls svc_sock_enqueue after setting the
SK_CONN bit. This doesn't actually do anything because the SK_BUSY bit
is still set. The call is unnecessary anyway because the generic code in
svc_recv calls svc_sock_received after calling the accept function.
