eal: do not panic on vdev init failure

Even if one vdev should fail, there's no need to prevent further
processing.  Log the error, and reflect it to the higher levels to
decide.

Seems like it's possible to continue.  At least, the error is reflected
properly in the logs.  A user could then go and correct or investigate
the situation.
