net: defxx: Fix missing err handling in dfx_init()

Browse Source 
[ Upstream commit ae18dcdff0f8d7e84cd3fd9f496518b5e72d185d ]

When eisa_driver_register() or tc_register_driver() failed,
the modprobe defxx would fail with some err log as follows:

 Error: Driver 'defxx' is already registered, aborting...

Fix this issue by adding err hanling in dfx_init().
