I don't think updating the FPGA from the root of the N300 is the way to fix this.
Use your host machine to have a normal connection to the N300 via Ethernet management port (DHCP or static IP). Once you have a connection that functions (uhd_find_devices executed from host or test with 'ping' command), update the FPGA by executing uhd_image_loader from the host. The SFP+ ports do not have a traditional "NIC" chip. The hardware controller 'lives' on the FPGA. Because both are non-functioning and internal root uhd_find_devices has no idea what device it is, I believe your current FPGA image is corrupted. No worrying though. Just re-flash the FPGA from a host machine and all should be fine.
