net/enic: set rte errno to positive value

Related to d9fff8a31, where rte_errno should always have positive
errno values.

Technically this is an ABI change since it fixes an error code
introduced in 18.02, but is minor and inconsequential.

Fixes: 1e81dbb5321b ("net/enic: add Tx prepare handler")
