net: bgmac: Drop free_netdev() from bgmac_enet_remove()

Browse source 
[ Upstream commit 6f928ab8ee9bfbcb0e631c47ea8a16c3d5116ff1 ]

netdev is allocated in bgmac_alloc() with devm_alloc_etherdev() and will
be auto released in ->remove and ->probe failure path. Using free_netdev()
in bgmac_enet_remove() leads to double free.

Fixes: 34a5102c32 ("net: bgmac: allocate struct bgmac just once & don't copy it")
