Subject: [PATCH net-next 1/2] net/xgene: fix Wvoid-pointer-to-enum-cast warning

'enet_id' is an enum, thus cast of pointer on 64-bit compile test with
W=1 causes:

  xgene_enet_main.c:2044:20: error: cast to smaller integer type 'enum xgene_enet_id' from 'const void *' [-Werror,-Wvoid-pointer-to-enum-cast]
