[PATCH] net: usb: asix_devices: Check return value of usbnet_get_endpoints

[Miaoqian Lin <linmq006@gmail.com>]

The code did not check the return value of usbnet_get_endpoints.
Add checks and return the error if it fails to transfer the error.

Fixes: 933a27d39e0e ("USB: asix - Add AX88178 support and many other changes")
Fixes: 2e55cc7210fe ("[PATCH] USB: usbnet (3/9) module for ASIX Ethernet adapters")
