net: usb: asix_devices: Check return value of usbnet_get_endpoints

Browse source 
commit dc89548c6926d68dfdda11bebc1a5258bc41d887 upstream.

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.

Found via static anlaysis and this is similar to
commit 07161b2416f7 ("sr9800: Add check for usbnet_get_endpoints").

Fixes: 933a27d39e ("USB: asix - Add AX88178 support and many other changes")
Fixes: 2e55cc7210 ("[PATCH] USB: usbnet (3/9) module for ASIX Ethernet adapters")
