[PATCH v2 4/5] net/dpaa2: remove ethdev device in bus device

[David Marchand]

Calling rte_eth_dev_allocated() is enough to retrieve the
ethdev device object.

This leaves no user of the ethdev field in the fslmc device object.

Changes since v1:
- dropped return on !eth_dev (this should be fixed in a separate patch),
