smb: smbdirect: introduce smbdirect_connection_qp_event_handler()

Browse Source 
This is basically a copy of smbd_qp_async_error_upcall()
in the client and smb_direct_qpair_handler() in the server.
They will be replaced by the new common function soon,
which will allow more code to be moved as well.
