amd-xgbe: Check xgbe_init() return code
[ Upstream commit 738f7f647371ff4cfc9646c99dba5b58ad142db3 ]
The xgbe_init() routine returns a return code indicating success or
failure, but the return code is not checked. Add code to xgbe_init()
to issue a message when failures are seen and add code to check the
xgbe_init() return code.
