stmmac: handle allocation errors in setup functions
If the allocations fail in either dwmac1000_setup() or dwmac100_setup() then return NULL. These are called from stmmac_mac_device_setup(). The check for NULL returns in stmmac_mac_device_setup() needed to be moved forward a couple lines. Signed-off-by: Dan Carpenter <error27@gmail.com> Signed-off-by: David S.
