net/smc: fix ethernet interface refcounting
If a pnet table entry is to be added mentioning a valid ethernet
interface, but an invalid infiniband or ISM device, the dev_put()
operation for the ethernet interface is called twice, resulting
in a negative refcount for the ethernet interface, which disables
removal of such a network interface.
This patch removes one of the dev_put() calls.
